Re: Thanos and Loki
This thread sorta fits a theory I came up with over at The Avengers sequel's news & spec thread. Perhaps, the mind gem is in fact used in the scepter Thanos gave Loki. And considering the scepter was last seen in Black Widow's hand, SHIELD may still l have it.
And in Guardians of the Galaxy, if Thanos is ultimately gathering the infinity gems then, getting the mind gem back could give him a reason to come to earth in The Avengers sequel. Just a theory.
