Time for tea! Alice will already start heading back over towards the train, though she's glancing back to make sure he's following as she speaks.

"Oh, you're the one having those?" Casually. So casually. And not even casually on purpose - no, this is just how casual Alice feels about the idea of people drinking blood. It's not like Natsuno is drinking it from a person, after all, so in that sense it's pretty much like any other drink around the train.

And sure, even though she already figured out he was a vampire, it's not like she's just going to assume all vampire stereotypes about him. Though it seems like this one is - at the very least - true.

"What do they taste like?"

Clearly a totally normal question.
