[ EU ] Batman gets a call from commissioner Gordon about trouble down at Arkham Asylum . As soon as he arrives he sees the culprit giving himself up to the police . He 's a security guard who has shot and killed several of Arkham 's frequent residents .

He entered at the usual spot. The Arkham bat signal saw more use than he'd like; coming in from the east wing allowed him a quick pass by the one of the cells he dreaded empty the most. 
 
 `` Of course.'' 
 
 He continued on with a new force behind his steps. There were always casualties... always. All the more reason to get the story and head back into the night. The city wo n't sleep until he finds that monster. 
 
 Every death is his fault. Every single one. 
 
 He entered the lobby at the tailwind of the conversation. Three body bags along the floor, the third larger than the others. Guards? Doctors? There was n't an employee in Arkham he had n't interacted with. Just more that he's failed. 
 
 ``... in custody now. He just... turned himself in. Put the weapon on the ground and waited for us to get here, Commish.'' 
 
 Custody? Interesting, but there could be any reason not to place him back in the cell. 
 
 `` Jim'' 
 
 `` Ah. Faster than I expected.'' 
 
 On quiet nights he found his patrols tended to linger in the area. Ever the epicenter. 
 
 `` He must be planning something, Jim.'' 
 
 There was a slight hesitation. Or confusion? 
 
 `` There's no plan. He just snapped. Honestly, we knew it could happen someday. A man can only take so much. We should have moved him.'' 
 
 A quick, albeit late, assessment of the room told him something was n't right. The tone was wrong. Officers joking casually. Less than delicate handling of the body bags. Jim's callous attitude. That third bag... 
 
 `` Where's Croc?'' 
 
 `` Third from the left.'' 
 
 No. He rushed out the front. He knew what to expect when he reached the car, hoping he was wrong. As he threw open the door all he could do was stare. Cash. 
 
 The resolution in his eyes. No remorse. 
 
 `` Every day he'd threaten them. Someday he'd get out. They always do. I did it for Thomas and Maria.'' 
 
 `` Aaron...'' 
 
 `` The wallet's in my locker. Make sure Thomas gets it. Tell him there's no reason to be afraid of monsters.''
