John Watson does not resemble a hedgehog. (what_son) wrote in valarlogs,
After maybe not-very accidentally knocking the man he was sitting on out, John followed Sherlock -- because that was what he did. His expression was one of vague confusion. "Not here?" he repeated, in question. "Then where?" It really begged the question of whether Sherlock had thought that in the first place, and why they'd bothered entering.
He was used to being a step behind though, and so didn't bother asking all that.
