Re: The Jaimie Alexander/Lady Sif thread
The major players and screen time in both Thor movies have been Thor, Loki, Jane...
Marvel has spent over 320 Million and counting on the Thor franchise alone developing that storyline, and they also took time out to explain Jane's absence in Avengers as well.
I don't see any evidence they are going to jump ship and push a breakup with Jane to make room for Sif..
Portman has stated she would be very happy continuing the role and Marvel will make sure that happens...
