I hope this one's easy to find - I'm sure it's been recced somewhere but I cannot for the life of me find it.
I'm looking for that specific fic in which it's discovered that Loki only attacked Earth for his child. It had vaguely cracky undertones, if I remember correctly, and Loki implied that he wouldn't have bothered with Earth if not for his child. He's also sweet and gentle to the baby.
Thanks in advance!
