Ever since bruce went missing it felt like he was going crazy,searching,searching searching. and then he came back,and along with him coming back was not his old job as Robin back. But a new mantle,Red Robin. But it always seemed like with Damian in the picture he was less and less welcome. Sure,Dick hung out with him from time to time,Jason didnt want to kill him. But Damian would always be Bruce's real son. Something none of the previous robins could compete with however much they tried. So yes,he did work himself to exhaustion. To prove something to himself. to everything. So when you found him passed out in front of the bat computer you decided to do something about it.
