I love the image of Remus and Sirius "having a snuggle" in the dark quiet room with the fire burning. Very tranquil, and yet tinged with pain and sadness because of Remus' illness before the moon.
Love the interactions of all three boys, as if they've done this all before and are familiar with their roles. I especially like how James cautiously approaches Sirius about searching Remus' trunk only after he's looked everywhere else.

And later, James is so sweet with Lily. I can see him really beginning to mature.
