Ok, I remember that victor was in another dimension and escaped somehow. He called the xmen for help and Scott decided to grant him asyl. Wolverine was against it and told so in uncertain terms. Victors claws were bound with a contraption so he could use his hands but not the claws and the metal was only cutable with adamantium. Wolverine had to cut them of and it was a really tense moment. I also remember that Victor pulled the matress in his room into the closet and built a nest.
The fic was not finished as I read it and it was on the way to get slashy I think. Also I'm not sure wich universe it was set in.
If you could help me I'd be really grateful because I'm searching for the last year already.
