It's been a while since you've heard from Bruce. He practically closed himself off from everyone else so he could finally embrace what he was. 

In his own words to be." The one they cannot kill."

First you've heard about the Joker aka Jeremiah Valeskas death.

Bruce didn't feel an ounce of guilt, in fact during a talk he even cracked a smile.

Victor Fries vanished but his weaponry was seen in the hands of someone new. A vigilante the GCPD  unofficially acknowledged and never pursued.

An attempt to spy on him ended up wasting all the equipment you purchased after he stomped on all of them.

You tried to figure out another way when Bruce appears behind you seconds later." Try harder next time."
