Kurama just sort of watches Bev as she walks out from the direction of the kitchen, a tad bit curious to see the water in her hand since she could probably just gotten some from her room. Then again, it's possible it's either not water, it's a filtered water, or any number of other factors that could be probable and likely. Honestly, he doesn't care a great deal, as she seems distracted and as if she doesn't see him.
It's a bit harder not to care, or take notice a moment later though, when she seems to react to... something. Something she is saying is 'not real?' Interesting.
She is lucky though, that as she turns to him with either hidden or visual embarrassment, the red-head only smiles warmly.
