Rainbow was getting ready for school and she wasn't feeling well at all, she had a massive headache and felt a little sick, she'd been feeling this way for a while but hadn't thought anything of it. She went downstairs to say good morning to her parents and sister, but when windy put a slice of toast in front of her she didn't feel like eating anything as her head was hurting too much.

Windy whistles: are you not hungry rainbow?

Rainbow: *groggily* n-no thanks mummy.

Windy whistles: *becoming worried* why not sweetie? It's apricot jam that's usually your favourite.

Rainbow: just don't feel like it.

Windy whistles: are you feeling alright sweetheart?

Rainbow: *sighs* I've got a headache.

Windy whistles: aww you poor thing, I'll give you some pain killers before we head to school.

Rainbow: ok.

Windy drove the girls to school and waited with them in the playground before the whistle blew. (pardon the pun) however she was really worried about rainbow as usually she would dart off to her friends and play with them, but this morning she just stayed at windy's side with her head resting against her. Finally the whistle went which meant it was time to go into class.

Windy whistles: *brushes back rainbows fringe to feel her forehead* ooh you feel a little warm sweetie.

Rainbow: *whimpers*

Windy whistles: listen baby just stay here for a little while, let the pain killers kick in and if your still feeling poorly later ask someone to call me ok?

Rainbow: *sadly* ok mummy.

Windy whistles: good girl. Love you.

Rainbow: love you too.

Windy kissed her forehead and left to go back home. Rainbow got lined up with the rest of her classmates and they went into the classroom.

*later on in the day*

It was after lunch and the class was now sat at there tables learning some new words for a spelling test they had to do on Friday. Rainbows head felt like someone was banging something heavy against it and she felt really sick. She was shivering and sweating, she started to hyperventilate which caught the attention of her friends.

Aj: rainbow are you ok?

Rainbow: *panting and crying* n-no.

Aj: *rubs rainbows back* what's the matter?

Rainbow: I-I f-feel s-sick.

Aj: ok, twilight can you go and get Mrs stardust please?

Twilight: yes of course.

Mrs stardust then came over them and asked what was happening. Applejack told her that rainbow wasn't feeling well and she knelt down to rainbows level.

Mrs stardust: rainbow sweetie is anything hurting?

Rainbow: *sobbing* m-my h-head!

Mrs stardust: ok ok shhh, can someone go and fetch the nurse please? And I need someone to go and get the sick bucket from the cupboard.

Sunset: I'll go and get the nurse.

Rarity: I'll get the bucket.

Mrs stardust: thank you girls.

rainbow started gagging and quickly covered her mouth with her hand, rarity quickly came back with the bucket as the cupboard was in the classroom. As soon as rainbow had it she started to violently throw up, fluttershy rubbed her back as she did so and told her that it would be ok. Mrs stardust had sent the other students to a different classroom to their work under the supervision of another teacher.

Mrs stardust: sweetie are you done?

Rainbow: *sobbing* m-my h-head r-really h-hurts!

Mrs stardust: *gently* shh I know it does, it's ok the nurse will be here in moment.

The next thing that happened shocked everyone rainbow collapsed off of her chair and onto the floor, well into Mrs stardust's arms.

Pinkie: *panicking* is she ok?!

Mrs stardust: I'm sure she's fine pinkie. Look the nurse is here now.

Nurse red heart was walking into the classroom and was about to come over and check on rainbow. But when Mrs stardust looked back at rainbow she noticed something wasn't right. Rainbow started to convulse quite badly, this really scared her friends as they had never seen anything like this before.

Fluttershy: *crying* w-what's h-happening?!

Nurse red heart: *rushing over and kneeling on the floor beside rainbow* she's having a seizure. Mrs stardust can you go and call an ambulance and I'll look after rainbow.

Mrs stardust: of course, and girls I need the 6 of you to go into the other classroom with the rest of the class.

Sunset: but what rainbow?

Mrs stardust: I know you're worried, but this can really distressing to watch and overcrowding her won't help.

The girls left and Mrs stardust went and called for an ambulance, nurse red heart had just put rainbow into the recovery position when the fitting stopped. However rainbow just laid there sobbing and screaming about how much her head was hurting. She suddenly felt really sick again, so she quickly sat up which hurt her head more and started to violently throw up into the bucket. The nurse rubbed her back as she sobbed and shook.

Nurse red heart: it's ok sweetheart the ambulance will be here soon.

Rainbow: *screaming* I-I w-want m-mummy!

Nurse red heart: shh she's coming as well.

Finally the ambulance turned up and the paramedics rushed to the classroom. They we're asking the teachers some questions and then asked rainbow if she remembered what happened. She shook her head which was really painful for her, and that's when windy came in and rushed over to her baby.

Windy whistles: oh baby are you alright?

Rainbow: *sobbing* n-no h-head r-really r-really h-hurts m-mummy!

Windy whistles: *rocks rainbow gently* shh i know it does baby.

She felt rainbows forehead again and this time found it to be burning up, she'd been informed of the seizure that rainbow had suffered,  and after answering any questions the medics had and after they did the standard checks on rainbow, they put her onto the stretcher and got her into the ambulance.

*at the hospital*

Rainbow had, had another seizure in the ambulance this one was bigger than the one in the classroom and seemed to last for longer. She threw up whilst she was laid on her side, windy was crying as she felt so helpless watching her baby girl in so much pain. Once they'd gotten into the hospital the medics rushed rainbow to the scan room and Windy went and met bow in the waiting area.

Windy whistles: *rushed to bow sobbing* i-it w-was a-awful!

Bow hothoof: *strokes his wife's hair* shh I know, but she's in safe hands she'll be ok.

They sat and watched as the doctors did an MRI scan on rainbow, the nurses and doctors had gotten rainbows seizures under control they were now looking for what had caused them and the migraine. Bow and Windy watched helplessly as their little girl was being checked over. Finally the scanning was over and the doctor left them alone to go and get the results, he'd put rainbow to sleep so that she wouldn't have any more seizures and also put her on a life support machine.

Windy whistles: *stroking rainbows hand* it's ok baby, mummy and daddy are right here.

Bow hothoof: *trying to joke through tears* you make sure you get better kiddo, do you hear me?

The doctor came back and took bow and Windy into a more private area.

Doctor: I'm afraid it's not good news.

Bow hothoof: what is it?

Doctor: rainbow has a brain tumour, that's what has been giving her a headache and what caused the seizures, I'm afraid it's been there for a long time.

Windy whistles: *collapses into bows arms sobbing* N-NO! PLEASE NO!

Bow hothoof: *hugs her tightly* is there anything you can do doctor?

Doctor: *sighs* we can attempt to operate and remove the tumour, but I would strongly advise against it.

Bow hothoof: *choking on tears* y-you mean she might die?

Windy whistles: *screaming* NO!

Doctor: Mrs whistles the brain tumour is too advanced, even if she did survive the operation she wouldn't be the same again. I'll leave you two too talk and I'll be back soon.

Bow hothoof: thank you doctor.

Windy was an absolute mess and bow was trying to console her.

Windy whistles: *sobbing* we can't let them take our baby away bow we can't!

Bow hothoof: shh I know it's hard, but I think he's right.

Windy whistles: *getting angry* WHAT?! you think we should let them kill our little girl?!

Bow hothoof: *crying angrily* hey of course not! But you heard what the doctor said even if rainbow did survive the operation and that's a pretty big if, she wouldn't have a normal life, I think we need to let her go.

After about an hour of arguing bow and Windy had made a decision, the doctor came back in and asked them what the final decision was.

Doctor: do you know what we're going to do?

Bow hothoof: what's the chances of survival?

Doctor: even if the surgery went well? Less than 50%.

Bow looked to his wife who was hysterically crying and then looked back at the doctor.

Bow hothoof: we've decided that we don't want rainbow to be in any kind of pain and suffer, that's it's best if you put her to sleep.

Doctor: *sadly* ok I'll go and tell my team, if you know anyone who would like to say goodbye please ask them to come now.

He left and bow and Windy sat crying in each other's arms. Loved ones came and said their goodbyes and bow and Windy were talking to the doctor.

Bow hothoof: so how will it happen?

Doctor: the breathing tube will be removed whilst the machine is turned off, and rainbow will peacefully pass away.

Windy: *choking on tears* W-will s-she b-be I-in a-any p-pain?

Doctor: she won't be able to feel anything.

Bow hothoof: how long does it take?

Doctor: once the machine is off and the tube is removed, rainbow will die in a matter of minutes.

Bow hothoof: *looks at his distressed wife* honey I know it's hard but we need to do this for dashie.

Windy whistles: *hiccuping*  o-ok.

*in rainbows hospital room*

The doctors were getting ready to turn the life support off and bow and windy were saying a final goodbye to their baby girl.

Windy whistles: *stroking rainbows forehead and crying* it's ok sweetie, mummy and daddy will see you again one day and i-I'm s-so s-sorry it had to be like this.

She kissed rainbows forehead and then got up so that bow could say his goodbyes.

Bow hothoof: *sniffling* h-hey, what Am going to do without my favourite little sports buddy? But no sweetheart it's ok you don't worry about daddy, you go and have a wonderful time up there in heaven and we will all be with you again one day.

He kissed rainbow goodnight one last time and told the doctors they could do what they needed to do.

*after the machine is switched off*

The life support had been switched off and bow and windy were left with their daughter, who was still alive but wouldn't be for much longer. Bow was stroking her cheek and whispering softly to her.

Bow hothoof: it's ok sweetheart, you can let go, you can die peacefully now.

Windy whistles: *held rainbows hand on the other side and sat got up and kissed her forehead whilst crying* night night baby girl.

A couple of minutes later rainbow died.

A/N: thank you to MidnightMice2005 for the tumour idea. It was my idea to kill rainbow off, it was a VERY difficult decision but I wanted to show that not all of the stories will end happily. If you want a story for her funeral let me know, and remember it's a random story series so rainbow will be back alive and well in future stories.
