After leaving Selina tied up in the GCPD the Batmobile rides hard in the city

With Batman and Robin in it

Next to them was Batgirl riding on her motorcycle 

Robin: You really think Freeze ain't pulling her chain? 

Batman: His only option is saving his wife. We'll worry about him after we stop Bane.

Robin: Hope you're right. 

In an abandoned subway Bane and his men were setting up the Sevier 9-6 

They had a stored crate of the TITAN formula and insert it in the bomb 

Bane: Excelente. The streets of Gotham will soon run itself down it's own knees.

Merc # 1: What if Batman shows up sir? 

Bane: Leave him to me. 

A second Merc ran in distressed 

Merc # 2: SIR! That Bat car is heading our way! Freeze must have snitched! 

Bane: No matter. Call in reinforcements and set the bomb to 30 minutes. But....leave me....the BAT! 

The Dynamic Trio soon entered the abandoned tunnel 

Robin: How does Bane expect to make a chain reaction through an abandoned subway? 

Batgirl: The level of grounds above is thin enough for a large enough out burst out from every sewer in the city creating waves of that.....Titan stuff. Whatever he calls it.

Robin: You're good.

Batgirl smirks

Batman: I don't suppose you know how to shut down a Sevier 9-6?

Batgirl: Well I have been reading on it. But I'm a memory lock. 

Batman: Already I feel confident. 

They proceed on their way but soon saw movement 

Batman: High ground. 

They grappled up and on the upper rails they heard talking from a distance 

They fallowed the voices and soon spotted Bane with the bomb speaking Spanish with the mercs

Robin: There they are. 

Bane confused his speech in Spanish and Robin couldn't make it out

Robin: What's he saying?

Batman: "In 30 minutes Gotham's rebirth begins in the hour of the fall. When the people taste the TITAN formula they will tare themselves apart through rage. And from the ashes of Gotham.....shall dawn a new Gotham. A Gotham without crime. Without murder. And our children and our children's children will look on to this day they will celebrate it every year cause they will know....they will never have to live in fear."

Robin: Jesus if Bane wasn't evil I'd be moved by that speech.

Batgirl: He probably doesn't think he's evil. He's probably just blind of all the pain and suffering here.

Robin: Evil's evil. I don't see how else he'd want to destroy Gotham. 

Clearly Robin was more black and white than Batman he wasn't approving of Freeze or Catwoman 

But now was not the time to get blunt Batman examined the timer on the bomb and they only had 28 minutes now

Batman: No time for stealth. We'll have to plan an attack. 

He sets on his scanner goggles

He begins linking planning an attack

Batman: I'll need you two to take those three right by Bane. I'll handle those guarding the bomb. And the three of us will take Bane together. Soon as he's away from the bomb Batgirl you'll need to disarm it with whatever you know about it. 

Batgirl: No problem. 

Batman: I'll go first.

Robin: Of course.

Before the mercs knew it The Dark Knight glides down

He kicked them down 

When the other mercs saw Robin attacks one from behind as Batgirl trips and kicks the other two 

Once Bane spotted them 

They charged him and Batman uppercuts Robin punches and Batgirl kicks Bane falls aside from. The bomb now 27:00 minutes left 

Batman: We got Bane.  You know what to do it. 

Batgirl: On it.

Bane stands up angry

Bane: Te interpuiste en mi Camino por Ultima vez. This time I'll break more than your back Wayne.  I'll break everything off your body. 

Batman: You'll have to catch me first.

Batman and Bane finally begin the final round

Robin attacks after the brawl starts 

Batgirl opened the panels with wires 

Batgirl: Ehhh....shouldn't be too hard.

The Dynamic Duo continue fighting Bane but it was a lot harder than before 

The TITAN formula made him into a human concrete

Bane grabs Robin's fist when countering a punch and threw him forward falling on the abandoned tracks 

Batman tries to stun him wit his grapple gun 

Hoping to hit his tubes but missed 

Bane grabs him and was gonna break him again 

But this time Batman quickly takes a bat taser and slaps it on his head

Bane was shocked he dropped Bruce and used the opportunity to pull the last of his tubes Bane yelling with the venom leaking out 

And soon enough....Batgirl had finished defused the bomb the loud ding gave it away

Batgirl: YES! 

Bane: NO!

With the bomb disarmed Gotham was safe from becoming a TITAN monster land

Batman: You lost Bane.

Bane: Yo creo que no.

Bane injects another TITAN dose in his vain

Bane: BREAK AWAY BATMAN! HA HA HA!
