Sally nodded at Lestrade's question. "Fine, Sir," she answered, and then paused to realize for the first time that it might be a bit strange to address him that way considering they were A) off the clock and B) on the wrong planet. She concluded that it would be weirder to suddenly stop.

She opened her mouth to apologize for assuming Jilly and Lestrade had met - Jilly just struck her as the sort of person who would talk to everyone new - but decided not to start. Instead, she smiled at Jilly's excuse for a walk in the woods. "They are very nice as trees go, but I really never would have gotten out of them if not for your help."

It occurred to Sally that they were still standing outside John's door. She caught Lestrade's eye and nodded to the door, eyebrow raised, silently inquiring whether he'd already knocked.
