Jason now understands the hallucinations Dick and the others described having after Jason died, except now, he sees you the latest young innocent Robin killed because of a villain, and it's Jason's fault. He had felt salty and spoke without thinking, saying you couldn't do anything on your own, making you run off at night to prove yourself, not to Bruce, yourself, the batfamily, no, prove yourself to Jason...
Jason now sits in his safe house, your giggles coming from everyone, yet nowhere, he knew it wasn't you, yet you looked like you did, sound the same, act the same, it's maddening. Dinah tells him to confront the hallucination of you, to in Jason mind, have you 'move on' to get Jason's mind to accept your gone.
"Kid– Just... Ugh... Show yourself."
Jason talks to himself, trying to get your hallucination to appear, to get over his guilt, to have you 'move on'.
