This is a bit out of nowhere, but I'm always desperate for a little insight into your choices, so I have to ask: Why did Grace choose Kaidan over Ashley? Was it because of rank, or friendship? The presence of friendship is strong with Grace and Ashley (it seems), and somewhat lacking with Kaidan, but he was chosen instead of her, so I'm curious.
Oh, man, this is kind of a fun question. Thank you for asking!
