Tethered Redemption by Maqeurious reviews
When God asked Odin if he wanted Loki to seek penance for his actions in NY, he said yes.

Harry Potter and the Time He Wasn't Actually Harry Potter by Alatar Maia reviews
..wait, what? Harry Potter not himself? Well, when you factor in a skewed ritual done by a dead person, an evil wizard, and a time-traveling baby, it starts to make a little more sense.
