Bruce's eyebrows lift at that last statement, but he doesn't remark. He pulls his gaze from where it's following Amy's progress across the lake, and sizes this...ghost?...up.

They really can't afford to let her out of their sight again. That castle looks way too creepy to be safe. So he lowers his voice, hoping the thing won't hear.

'We have to keep going. I don't think ghosts can hurt us.'

He doesn't like to underestimate an opponent, but it's either turn back, or put their foot down with this creature. Or fight it. And turning back isn't an option.

'Just start walking.'

And that's exactly what he starts to do.
