Author's Note: Okay, so I feel like the epilogue might need some explaining. Details at the bottom, for the sake of avoiding spoilers.
Five months later, Loki was living happily at the tower. Odin, Frigga and the Avengers had all decided that it wouldn't be a good idea to rip Loki away from either of his families, (lack of blood relation notwithstanding) and so they had worked out a sort of joint custody thing; weekdays were spent in New York with the team, and weekends and Asgardian holidays were spent in Asgard. As Bruce had said, second chances are rare; so everyone made sure that Loki's counted. And though his family wasn't conventional, (most people don't have four dads and four moms, not counting Darcy, who is more like an aunt, and Thor, for obvious reasons) He was happy.
Ever since the incident in Asgard, everyone made sure that no secrets were kept from Loki. They probably shouldn't have forgotten in the first place that there was a reason he was sometimes called "The Liesmith". Not only could he craft them expertly, he could smell a lie a mile away. Of course, there were always little things that were left out accidentally. Like one day, when Loki was exploring the mythology section in the library.
He had, of course, wandered over to Norse mythology. Loki was still Loki, and he loved reading about himself. Until he got to a particular page which made his face whiten. He ran back home to the tower in a panic, and burst through the door.
"Whoa, little guy!" Tony said, putting down his coffee as Loki marched up to him.
"What is this?" Loki demanded, holding up the book.
Tony snorted when he saw the picture; he had gotten to the part about the stallion, Svaoilfari. "Um, I think that's for your brother to explain. Jarvis, get Thor down here, would you?"
"Yes sir."
Thor arrived quickly. "You called?"
Loki quickly presented the book. "Brother, tell me it isn't true!" Thor saw the page, and immediately turned red in the face as Tony burst out laughing.
Author's Note: I'm not gonna lie to you, this is a bit of an inside joke. In Norse mythology Loki is supposed to have transformed into a female horse at one point and gotten pregnant by a stallion, resulting in the eight-legged horse Sleipnir. No joke. So my girlfriend and I have this thing in our roleplays where she'll say, "Loki, did you really have s*x with a horse?" And I'll say, "Oh, but you should have seen that stallion." So this is kind of an homage to her. I guess. It's also pretty funny, in my opinion.
