Probably not. But since Maedhros himself can get somewhat paranoid at times it's not completely out of the question either.

Maedhros follows at a sedate pace. The bite marks on the fish makes him stop short for a while, but he figures since Selkies seem to be some sort of oceanic creature it should not be too surprising raw fish were part of their diet.

It also does not completely surprise him she's not all that eager to reveal herself to them. Considering one person has already robbed her of her skin it is understandable that she might be a tad suspiscious.

Figuring she's likely the one observing them from somewhere nearby Maedhros decides to see if declaring their intentions might make her more comfortable with approaching them. "There is no need to fear us, milady. I assure you that we mean you no harm and have come instead in the hope of being able to render you what aid we can in retriving what has been stolen from you."

After that all they can do is wait and see if she'll believe his words.
