Thankfully, Remus has managed to keep a level head through it all, from calming Sirius down from a frenzy to holding him as he whispered about his nightmares in bed. Remus is anxious about it as well, of course, and Sirius can tell in the careful way he holds himself and the way he sweeps his eye about a room when he enters it, as if cataloging the various imperfections; Remus does not express his nervousness, however, not in the way Sirius does, and therefore balances him out in the best of ways.
