Re: Avengers 2 News, Rumors, Etc. Pictures until release...
It kind of makes sense to utilize Thanos in GoG since one of the characters is his daughter after all.
A lot of people are assuming just because Thanos was shown in the end of Avengers meant he was being used for the sequel. Not it appears that they were just setting up another Marvel film, in the same way the end of Iron Man 2 set up for Thor.
Don't believe everything I say.
