Yeah, Thunderbolts is definitely after Defenders as those two month old pages prove. And Photon is after that. Note that her Thunderbolts costume includes his jacket. Makes sense that the name she adopted when they met and the costume that includes part of his are both dumped when they split up.
Not true, the timeline doesn't work and that Defenders team ended with the book.
Isn't Jericho spoken for? He's with Scarlet Witch, right?
