He sent this to Grimes back when they were fighting publicly a few years back and she claimed he'd kidnapped them or something like that. Anyways, you see the other kid passing by him just out of frame. Nah, it comes off as an irresponsible d-bag when he does it. Considering he doesn't see them very often as it is and that this was sent ti taunt Grimes cause he hadn't returned them by the end of his arranged visitations.
