The Ties that Bind (слэш)

Tony Stark is sure it was Loki that saw him through the night before Pepper's funeral, even if he's talking up the uncertainty with the team. That's because he knows he owes Loki a debt for helping pull him back together and he really doesn't want to hear Steve's lecture about being compromised. Fortunately for him, when Loki decides to call in that debt it doesn't actually involve anything he finds morally troubling.
