Sephiroth is probably one of the last people David would expect to be ushered--willingly even--into the boat with him. He definitely seems more chill than usual. Still careful to arrange his hair so he isn't sitting on it, but otherwise unconcerned about the proximity or the fact that he's about to go into something called the Tunnel of Love. He's not smiling, but his expression is relaxed, the sort that could easily become a smile.

As the ride starts to move, he glances over the side of the boat. "I've seen my share of polluted water. It seems all right."
