About this "brother/sister act"...

So Whedon's hinted at some appearances coming in Avengers 2.

Everyone's talking about this...

...but NO ONE is talking about this...

...so I think, in order to avoid potential legal issues with Fox Studios, Whedon's "looking to the North" so to speak. Because even if Puck does appear in X-Men: DoFP, the Beaubier twins won't.

Two words...

'Nuff said.
