Remus was in the abandoned women's bathroom where Moaning Mrytle resided in. He was trying to keep himself busy as the other Marauders were away doing their own thing for the day. He was chatting with Mrytle to pass time.

"And then I told him-"

His sentence was cut short with footsteps entering the bathroom, which was unusual due to the bathroom being rarely ever visited. Remus got on the toilet and peeked over the stall wall to see who was coming.
