Ah, another pirate. The tattoos, the sword, yes that all makes sense. After the fact, mostly, because as observant as he can be, Watson has never been quite as good at reaching conclusions as Holmes, but grant him the awareness to recognize a swallow as being a particularly nautical tattoo.

Izzy probably looks more like his notion of a pirate than... probably anyone else he's met.

"Is that so?" Watson tries not to smirk. Polite smiles and dry humour only. "Well, do please try to avoid stringing people up by the ankles, Mr. Hands. It only creates more work for me, and the doctor-patient ratio on this ship is rather horrendous."

He tucks the towel into the pocket of his tweed jacket, and settles into a resting posture: at ease, in the military sense, back straight with only the illusion of repose. Watson's momentarily had his cane looped over a forearm, but he passes it into his left hand, taking the weight off his right leg.

"I suppose this is the grand tour you're getting? You seem... new, if you don't mind my saying."
