Ok this is what I remember:
Odin and Thor go to Loki for help in defeating an enemy that does not follow logic and they cannot seem to form the right tactical plan to defeat it and I think Loki figures out or Odin says it that he plans to put Loki on the throne cause he is going into Odin sleep. At first no one was happy cause Loki just sent Sif and other people to a random place and as he was telling people to swear allegence to him they got word that the group he sent was actually winning though they needed back up, but Loki said he can't do that since no one swore to him. I remember a couple of scenes where Loki threw a knife at a map I believe to choose the next place to send the troops, golden apples on the side of the road, and tentecles coming out of portals.
Hope that helps in the search
