Yes, I know, Procrasticritter. I did all that. When I emailed her agent, though, I assumed she wouldn't know exactly how many lines Alesia was doing, so I asked if Krystal was playable on the off-chance that the agent would know.
When I emailed Alesia, I asked about how many lines she had. I asked about the dialog in general, but I doubt she would be willing to say anything regarding her actual lines, considering she's probably supposed to keep it a secret. Specifically, I asked how many different grunts she had to record. I figure that if the number is higher than about 10, Krystal must be a playable character.
I've got it all under control.
