Before putting him in the tub (or the sink rather), he donned his little towel and I couldn't help but think he looked as if he was going to a toga party. Granted he doesn't look as good as Adam (Holmes) because well...Tristan's is blue (not too authentic), but I got a good laugh out of it.
I don't want you to get the wrong impression. Tristan is NOT scared. He's just a man of many faces, and this one is just one he makes in the tub sometimes. This is actually the "your hands are too cold to be washing me down there" look.
