My Kingdom, My Realm, Thy Will Be Done

From Avengers Assemble:

Loki casts a spell that causes time to rewind, but with a few drawbacks. Some people from alternate realities come into the mix, but who? Depends on situations, however these people disappear without a trace right after those situations are solved.

However, Loki finds one particular person who is different from these other alternative realities... as if she has knowledge of these situations before they happen. Loki tries to sway her to his side without much luck. Possibly using his best tactics like force, threats, you know the usual when it comes to Loki. The last resort Loki would ever use is sympathy. Vulnerability is a tactic Loki would only use if there was no other alternative route to achieve his goal.

As for the girl, she's just so excited to be there with a few of her favorite heroes.
