[Elsa isn't sure if it's just her own personal paranoia, worried for years about revealing her powers, about hurting others without intending to, coupled with her actual experience of being chased and threatened, called a monster for just one slip much like the one she just had... Or if there is really a threat in the man's words just now.

She tries to not make judgements based on appearances or attitudes, and she questions the efficacy of threatening someone who just admitted having problems with their control under situations of panic and stress. It would be like throwing someone who started shooting at everything around them and had claustrophobia into the tiniest barrel they had. So maybe it is just her after all, she can't deny to be almost counting the minutes before someone points at her and yells "monster" before chasing her away just for being there. At any rate she's sure that she doesn't want to know which is it, so she merely nods in understanding, all signs of her inner discomfort being reduced to her hands tightening their hold against each other in front of her and a small increase of the extension of the faint trail of ice and snow that she leaves whenever she moves.]

I will, it's far from my intention to damage the ship or our crew, after all. I also have no wish to be a hindrance rather than a help during the travel, at least no more than what I already am with my lacking sailing knowledge.
