Well Remender had said in the Final Execution interview that Betsy and Wolverine would come out of the arc changed and in a completely different place. He also said someone was dying after issue #27 (not in issue #27). The fact that Fanto is chained up looking bleak on the cover of 27 doesn't indicate it is him. The fact that Betsy is alive and well on the cover of 28, doesn't indicate she's safe yet. It may not be until like issue #30 that someone bites it. On a personal level, I'm still hoping it is Fanto or Deathlok, verses any of the others though.
If Betsy goes villain, that would definitely be a completely different place. That could well be it, and she pulls the trigger on Fanto.
Or if Fanto dies, it might mess with Betsy's head even more as well, but as far as impacting Wolverine, only the degree to which it might impact Evan, I would guess. He has lost friends before, and closer ones, without it driving him over the edge or taking him in a different direction.
Did anyone else think of the impact Mystique (on the cover of 27) might have on AoA Crawler? He was shown to be pretty nasty this issue and stated that he would have been willing to see this world burn just to kill his friend. Maybe he jumps in with his Mom and that prompts Wolverine and Bets being in a different place. (Unlikely yes, but stranger things have happened.)
