Nope.
Option A: Continue yelling at Dia. This will shatter her emotionally. She is very submissive and will do as asked, but it won't be the best option for her mental state. But it would be the easiest for Caro.
Option B: Calm down and try to keep from scaring her anymore than she already is. Eventually, she will calm down. But it may take a little while, and every second counts.
XD I'm mean aren't I? Making you chose between keeping Dia sane and potentially letting Aki die or saving Aki right away and adding more issues to Dia. That's mean, wouldn't you say? :P
