Minutes passed... maybe hours?
Neither Robin nor Billy felt the passage of time as if time had completely stopped around them
For Robin, this was his only chance to ease his heart even by a little bit, the first time he had a chance to talk about it since that dark day.
After confronting the All-Seeing God, Robin surrendered and accepted the reality that everything that happened was collateral damage that should be forgotten, but he never got over it. And even if he got over his dead wife, how could he get over Richard who was still alive? Maybe if he had died with his mother, getting over it would have been much easier, but now? To say that the issue is complex would be an understatement.
Richard represents everything Robin hates! and at the same time everything he loves...
