Doesn't Play Well With Tricksters

In this alternate universe, Loki has been exiled to Midgard when Odin sees through his disguise (Think the end of Thor, The Dark World). He is haunted by his part in the death of his adoptive mother. He has visions of her that may be her talking to him from beyond the veil of death or just his overactive guilty conscience playing tricks on him. Either way, he has promised her he will do everything he can to make up for the things he's done. Even if it takes until the end of time itself.

As part of his penance, Loki is restricted to Stark Tower until such time as the team believes he is no longer a threat to the world. As it gives him the opportunity to try to keep his promise, he doesn't argue. Much.

Rachael has recently acquired magic from a relative. Shortly after, she was recruited by Stark and moved into Stark Tower to help the team. It's the one place she would never have expected to encounter the God of mischief himself, who happens to be the root of the magic she doesn't trust.

(Long story short, Rachael's ancestor Bridgette fell for Loki when he was on Midgard nearly four hundred years ago. Eight months after Odin ordered his sons home, Bridgette had a daughter. Skip about five years of wishing for him, and Bridgette accepts that he's not coming back. She marries and has other children. One of these later children is Rachael's ancestor. The elder child is the ancestor of Rachael's distant cousin Nicolla, who was adopted by Rachael's grandmother and raised as Rachael's aunt. Still confused? Leave a note and I'll try to clear it up for you.)

Missions start to come in that force them to work together, and force her to admit he's doing what he can to make up for the destruction he's caused.

At first, Rachael refuses to acknowledge the attraction she feels, but he, being the annoying godling he is, seems unable to take no (or a stiff right hook) for an answer.
