Family Reunions (слэш)

When a freak accident raises questions about Tony's mortality, the Avengers find out there's a reason why Tony always survives his self-destructive heroics. Tony thinks he has the worst luck with dads and wants to just crawl back to bed with Loki. As for Loki... He just wants his lover to keep his promise and stay alive for a change.
And to think, it's all because of Clint's dog.
