But Cyclops wasn't really that extreme. Except for when he was posessed by the Phoenix, he wasn't that bad. A lot of his behavior seems exaggerated by fans and writers.

It just seems dangerous for Laufey and Malekith to keep Loki around. Of course, given Loki's new status with Wolverine, who knows if that will be Loki or a Loki-offshoot.

The new news from the X-Men side also shows that a Wolverine will be involved in their Age of X-Man event. That event will go on for five months, meaning there's a good chance for overlap and we won't know the exact status of the X-Men during this time. This could imply that the Wolverine in the WotR is in fact not the 616 one, or it means the Wolverine in AoXM isn't the real one. So fun!

I guess my thing is, if Laufey suspected Loki wasn't his, would he keep him? Especially since he hated Loki and Loki had nothing to offer as a boy? If he thought his wife cheated with Odin, would he have allowed that child to live? And would no one not have noticed them missing?
