“Where have you been?” Lily asked James and Sirius.
“What have you done is what I’d like to know,” Remus said.
“We caught up to the prats after Madam Pomfrey came and er, well we showed them what we do when people sod us off,” James said, smiling.
“You haven’t answered us,” Remus said, breathing out a small laugh.
“Well they cast that spell on you so we thought instead of cleaning up the mess YOU left on the ground that uh,” Sirius said.
“We washed their mouths out!” James said, laughing.
Lily and Remus exchanged glances, and even cracked a smile. Lily started laughing, and said “You finally used it on people who deserved it, then.”
James shrugged and smiled at her.

“Okay you three, OUT! Mr. Lupin has some healing to do and he needs his sleep, now out!” Madam Pomfrey said briskly, and they said goodbye to Remus and left.
Oh the way back to the castle, James had his arm around Lily and she didn’t protest.
