Robin follow the trail to Sionis steel mill.He sees guards with snipers and machine guns.He grapple a rooftop and he pull out a few batarangs and spray the explosive on them.Then he throws them to all of the guards and donated them.All guards were knocked out by the blast.Robin glide down to the entrance and enter the steel mill.Guards were there but with no weapons,so he took them down with his martial arts.He switch his vision to x-ray and look around.He look at the office and see dozens of people in there.Even see a man with powerful weapons on him.Robin concluded that it was Deadshot.He return to normal vision and went upstairs but then get block by a turret.It blasted bullets at him but he took cover.

Deadshot:"Someone is here.Keep your guard up."

Robin look around and see an open vent.He climb inside of it and crawl all the way to the office.He sees Deadshot and his thugs,so he glide kick Deadshot and start fighting with his thugs.

Meanwhile

Batman,Batgirl,and the second Robin arrive the steel mill and saw the guards on the ground.Batman walk over to one.

Batgirl:"Are they...?"

Batman:"No,still breathing."Batman sees a batarang and pick it up.He saw that it was damage and knew how."He used the explosive gel on the batarang."

They enter the steel mill and hear fighting sound.They ran upstairs,disarmed the turret,and enter the office to find Robin fighting with his sword,goons everywhere,Deadshot on the floor,blood on the ground,and bodies also on the ground.They enter the fight.

A seconds later

Batman:"What do you think you were doing?"

Deadshot start standing up carefully to make no noise while they argue.

Robin(Damian):"Trying to kill Deadshot."

Batman:"Killing is not the way to deal with enemies."

Robin(Damian):"This is not about dealing with enemies.This is about protecting grandfather."

Batman:"This is not the way to protect him.This give his goons to be outrage with Ra's al ghul.They will not stop until he is gone because you took their leader.Every killing got a consequence."

Robin(Damian):"Then we keep fighting to the very end,only one team must live."

Batman:"But if you kill him,then you will not know who hired him to kill your grandfather."

Damian look down then sigh and look up.

Robin:"Fine.We'll question him."

Deadshot start blasting his bullets.They dodge it then hide behind cover.Batgirl throw a batarang but Deadshot dodge it but then Tim zip-kick him.

Robin(Tim):"Well,that was easy."

Few minutes later

The police drove Deadshot to G.C.P.D while Batman,Robins,and Batgirl standing on a random rooftop.

Alfred(Over the com):"Congratulations.What now?"

Batman:"Me,Damian,Talia,Tim,and Barbara will go to G.C.P.D and to question Deadshot.Tim and Barbara will stay outside of the room."

Talia(Over the com):"I'll be right there soon."

They start going to G.C.P.D.

Few minutes later

Batman,Robin,and Talia enter the room while second Robin and Batgirl stay outside for guards.

Deadshot:"No coffee?"

Batman:"Who hired you?"

Deadshot:"Can't spill costumer.You know this works,bats."

Talia slam her hand on the table.

Talia:"How about I slice your fingers first and see where to go there?"

Deadshot:"Ooh.Is daddy little dragon learning to spit fireball?"

Talia draw her knife out.

Talia:"Do you want to see how much I learn?"

Batman:"Talia,calm down."Talia put the knife back."You really don't want her to be angry.Let make this easy,Joker said that you wanted the boy."

Deadshot:"Yes,so I can drag her mother out and I can use both of them as hostages for Ra's.I'm sure he will sacrifice his life for his daughter and grandson."

Robin:"How did you know I was his grandson?"

Deadshot:"Through out the years of Batman having sidekicks.Innever seen one of them using a sword,so it was easy to put it together."

Batman:"Very good observation.But there something you forgot to notice."

Deadshot:"What is that?"

Batman:"You gave away clues to your boss,and now I know who it is."

Deadshot:"You really don't know."

Batman:"Do I look and sound like I am joking?"

Deadshot:"No?"

Batman:"We are going to find him and tell him that you fail to keep his secret."

Deadshot:"Wait,no.You don't know what Deathstroke will do to me.I....you were just pretending to know who was my boss,so I can tell you who it really was."

Batman:"Nice doing service with you."They turn around except for Talia.She walk toward Deadshot,grab her knife and pointed on his neck.Deadshot scream and they turn back around."Talia,don't!"

Talia:"This is just a warning to Deathstroke."

Robin:"Mother,don't.It is not worth it.A man choose it,a slave obeys.He was just a slave and not the man,the man can choose another and the slave will obey him.It will not change his mind if you kill him."

Talia thought about then put the knife away.

Talia:"You're right."

Everyone leaves the room.

Batgirl:"So,what now?We chase Deathstroke next?"

Batman:"No.The last time I heard anything about him is Amanda Waller is using him for her suicide squad."

Robin(Tim):"Wow.I kinda feel sorry for him."

Talia:"It doesn't matter.We came for what came for,so it is now time to go.I'll give father a call."

Few minutes later,at the rooftop of the hotel

Damian was looking at the city of Gotham without his mask.

Talia:"I guess this is goodbye,beloved."

Batman:"For now,there always trouble following you three."

Talia:"You too."

Batman:"Because I'm Batman."

Talia:"Yes.I guess so.Damian,come on.Say goodbye to your father."

Damian turn around and walk toward Batman.

Damian:"I'm staying."

Ra's al ghul:"What?"

Damian:"I thought I wanted to be an assassin,follow your footsteps.But then I thought everything I learned by father,and to be honest,it was...interesting and impressive.I want to stay and learn more of it."

Talia sigh.

Talia:"Make sure to keep an eye on him.He still got your stubbornness."

Ra's al ghul:"Talia."

Talia:"He won't be weak,Father.He'll be more advanced."

Batman:"I will take care of him."

Talia:"But we both know you also can't keep him forever.One day,you have to let him go to make his own journey."

Batman:"And when that time comes,he will already know how to be a good Robin."

Talia nods and a smoke bomb appeared.When the smoke appeared,they were gone.

Few minutes later

The Batwing fly through the water and lands.Batman and Robin walk to the bat-computer and see Alfred,Barbara,and Tim.

Alfred:"I see that master Damian is staying.Good.But now it will be confusing with master Drake."

Tim:"Actually,it weren't.I'm thinking to change my name to Red Robin."

Barbara:"Like the restaurant?"

Tim:"Yeah.What do you think?"

Batman:"It will be easier to separate you two."

Barbara:"I guess.Anyway,good night."

Alfred:"Good night,miss Gordon."

Tim:"See ya,Barbs."

Barbara leaves the batcave.

Tim:"I better go too.Night."

Alfred:"Night,master Drake."Tim leaves the batcave.Batman start fidgeting with the bat-computer."Master Bruce,before you go out.I need to tell you that I made a new suit for you."

Batman:"Really?"

Alfred:"Yes."

Batman:"Check every frequency for anything."

Robin nodded and Batman went to the change room and see the new suit.He start putting it on.

[There should be a GIF or video here. Update the app now to see it.]

He walks back to the computer.

Batman:"Thank you,Alfred."

Alfred:"My pleasure sir."

Robin:"Doesn't that look weak?"

Alfred:"Well,it go-"

Officer(Over the radio):"We got trouble in the docks."

Gordon(Over the radio):"Penguin?"

Officer(Over the radio):"No,sir.It's new."

Gordon(Over the radio):"On my way."

Batman:"Come on."

Robin nods and they enter the batwing and leaves the batcave.
