   Summary

   Sirius knows something is going on between Remus and James.

   He sees it in the looks they think no one notices, in the spaces between their words.

   But Sirius' mind has betrayed him before. It's distorted things, convinced him of things that weren't real. So when Remus tells him he's imagining it, Sirius swallows his doubts and lets himself believe the lie.

   After all, who is he to trust himself over the person he loves?
