The druid in spider form leaves that room, climbs up the wall back to the ceiling and across to the southern wall, then down and slips in between the door and lintel, squeezing into another guest room, this one with two beds.
The Spider-Theran scurries back out of that room, up and across the ceiling, and under the lintel of the next room across the passageway (to the north).
Theran moves on, slipping down and around the door in the south wall, moving back to the passageway.
Hurrying, he crosses to the closest door: the one directly to the south across the passageway.
The spider crawls back out and investigates the last two doors in the hallway. Thankfully, both rooms are unoccupied.
Theran hurries back to the room at the end of the hall with a cold chimney. He climbs into the fireplace, up the flue, down the outside of the chimney, across the roof, and down the side of the Inn building. He crosses the yard and arrives back at the barn just as his Wild Shape runs out. Reptile is slightly surprised when Theran reappears in front of him suddenly.
