Well, the promise was that the last page of Legacy #1 would break the internet. Wolverine wasn't the big return. Franklin and Valeria were.

Axel Alonso:
"That story functions as a preview of what's to come. It's chocked full of twists, surprises, Easter eggs, and let's just say, a last-page reveal that's probably gonna break the internet."

I can see this making a lot of FF fans happy (or at least hopeful), but there really aren't many of them, so I have to wonder if it will break anything.

We all knew Logan was coming back. It's not really the "easy path." I just don't understand how he did it. He shouldn't be able to just claw himself out of his Adamantium statue. Who or what broke that statue?
