We know this takes place right after the mini. So For now, it's no indication of where those two are actually heading. But who knows? Things might change after these current arcs in Legion and Tec.
I know Super Sons is the lighthearted book but I actually would love to see those two reflect on everything that happened to them after they split up. One of the things I loved most about Tomasi's Batman and Robin were those moments where the Bruce and Damian had those serious, character developing discussions in between their adventures. It'd be nice to get at least one moment like those in Super Sons. Though that could just be me being a sucker for sappy moments and relationship building between characters. It's part of the reason I loved the Wolfman and Johns eras of the Teen Titans lol
Bendis has already undone the "torture" by acting like that wouldn't have any long term effects on a child's psyche -___-
Most of the bad things that happened to Jon while he was in space has been swept under the rug. Because I guess the "how" was never important. He just needed a reason for Jon to be older.
