Rowan points out to Moss the direction the tendrils seem to be headed, gesturing with a finger and following one of the lines for him until it continues out into the water.  He seems to be focused more on the water itself, and she hopes bringing his attention to the underlying problem will give him a clue as to what it might be.  "If I were the kind that could breathe under water, I'd say the logical plan would be to follow and see where they go, but I can't do such things.  Not naturally, and my magic doesn't work that way.  Does your kind have a way of doin' such?" she asks, unsure of just how he might differ from her, other than the obvious shell, and his collection of mushrooms growing on said shell.  She ignores the elf, knowing by the look he gives the both of them what his opinion of them is, and she doesn't care particularly.  She's one to listen if someone has a valid opinion, but she's not one to go out of her way to make friends if someone's dislike is so obvious.
