Holy hell, scenes like this one are so refreshing, characters actually talking to each other about the situation and asking relevant questions, I hate it when the plot goes all Disney-like with people lying or omitting facts for no reason, their stupidity the driving force of the plot.
Also, there's obviously something wrong with that girl. I know people are right to say Reiji should just get the hell away from her, but I'm glad he's trying to get to know her better. I want her too to be okay.
