That's a tricky question, Caitlin thinks to herself. There are a lot of things she could speculate, but she's not really sure where to settle for a response because she doesn't know enough about this place yet to be sure. The thing is, there are an infinite number of possibilities and that sort of array of choices always tends to be the sort of thing that locks Caitlin up a little. She is forever a victim of the Paradox of Choice.

So she waits for a moment, considering quietly as they walk, and the expression on her face does at least suggest that introspection with the way that she chews thoughtfully on her bottom lip and her brow creases. "I mean, honestly, I don't know enough about this place to know if my speculations would even be applicable here; I can only go by what would be potentially possible back home. So that means it could be anything from this place's equivalent of climate change to a metahuman manipulating the atmosphere to create a distraction meant to keep from being caught doing something he or she shouldn't be doing."

Caitlin pauses there, looking over at him rather than just in front of herself, and she reaches a hand up to push more wet hair off her face as they catch up with the rest of the group. "But I don't know, obviously, for sure. It does admittedly remind me of something that happened back home which could suggest the latter, but..." her voice trails off and she shrugs.

Somehow it feels like expanding on that in the presence of the rest of the group is a bad idea. For all she knows, she could cause a panic over nothing. This could be a natural weather occurrence that just happens to be enough of an anomaly that the locals are uncomfortable with it. There's no point in unnecessarily stirring up worry in the whole of the group if she doesn't know; she's just guessing.
