Its as if he's just slapped her, Scarlett's head snapping back. Her eyes widening with surprise that fast turns into incredulity. His handler. She swore to god if this shit was happening because he seriously thought -

"That dickhead is not your handler." A few choice puns playing on the tip of her tongue but - time and place and all that.

"No." His words while utterly reasonable to anyone else, are met with a derisive snort from Scarlett as she turns away from him. Setting her lantern on the ground and just having to hope that some idiot doesn't kick it and send her towards a ridiculous death. She's too mad to look back at him as she starts to stalk away - while perhaps not entirely at him, still very much in the general sense.

"I'm getting back on that ferry. You can either come with me or you can watch from the shore." Because it's not just people to be saved here and now. There's a decent number of people around to help with that. It's also the fact that the only source of food they have is about to be lost to bottom of the lake and unless they wanted to recreate Lord of The Flies, they were going to have to do more than just get out of the way.
