LOL for Carolyn's line!
Welcome to Timothy Gordon!!!, appearing as the restaurant customer who chats with Maggie at the counter and uses the hotel stairs. Gordon had some memorable uncredited parts in his nearly 30 DS appearances-- besides also showing up in the Blue Whale, it's his hand that we see in #210, and he was the menacing hand of Petofi and (again) Barnabas, a spectator at a certain hanging, a 1795 family servant, the wedding minister in a particularly nasty dream, and [spoiler]Jeremiah's ghost.[/spoiler] TG attended some of the earlier Fests.
Since the lobby set was used for this ep, the phone booth has returned to its proper place. And there's now a number on the door to Burke's suite, but is it #24?
