2. Sif And Jane Foster Aren't Going To Get Along
The trailer strategically places a piece of Jane Foster's dialogue over the above image of Sif. This would suggest that, just like in the Thor comics, there is going to be something of a rivalry between the pair as they vie for the romantic attention of the titular hero. This will add a new dimension to a Marvel movie, as love triangles haven't really been explored fully in the MCU thus far. Jane Foster may well learn that Sif - an accomplished warrior - is not to be messed with. While it will also be interesting to see what she and her fellow Asgardians make of Darcy Lewis (Kat Dennings) if they ever meet her, given how she provided the (almost annoying, but fairly likeable) comic relief in the first Thor movie.
