Hay Braz, check my ending out.
Batman is looking up the moon on a building near the Bat signal and Catwomen comes to greet him.
Catwomen: Long Night huh.
Batman: I have had loads of long nights recently.
Catwomen: So what`s next.
Batman: The future is uncertain Selina, crime never rests, the Joker may be in Arkham but Black Mask is still out there. Gang warfare just seems inevitable each passing day.
Catwomen: I meant about us, Bruce are afraid to let me in.
Batman: It is not that Selina. I always be Batman and committed to fight crime and love with not get in the way.
Catwomen: This is not you Bruce.
Batman: Bruce Wayne died years ago, Batman is all I am now, Bruce Wayne is just a mask I am wearing.
Catwomen: Bruce thinks, we are who we are but it does not mean you have to shut yourself out.
Batman: Selina, I left my normal life years ago.
Catwomen: Well Bruce the day you have decided to become Bruce Wayne again that will be the day I will be back. I am leaving Gotham City.
It starts to rain, Batman and Catwomen both kiss each for the final time and then Catwomen goes of into the night. Batman meanwhile activates Bat wings and glides of the building into the night. Roll Credits, Bat symbol with title Batman Escalation.
