Thor and Loki team up. Villain fails to kill Jane Foster, and then Loki gets killed, villain will be killed also, and Thor and Jane Foster will be toghter and both are happy. This is what is going to happen.

I already hated Iron Man 3, when Pepper saved Tony Stark twice, got superpowers, and killed *beep* villain.

We dont need another crap where Loki becomes friend with Thor, and maybe even sacrafice and dies to save Thor and Jane.
