"Don't give me that look."
Lily shrugs, but keeps her hands tucked firmly behind her back. "What look?"
"Mostly blank, a tinge of flirty," James explains, hand twirling uselessly in the air.
"I don't give that look, and if I did, I wouldn't be giving it now because I've done nothing wrong."
Sirius snorts, which earns him a brief glare from James but otherwise no negative result.
"If you're not up to something, then show me your hands."
Lily glances over her shoulder at the portrait hole, then quickly toward Sirius, and then finally a desperate look somewhere behind James. It only takes a handful of seconds for the quick succession of panicked looks and then she yells, "Peter grab him!"
