I count three important ones for dds? Maybe the first isn't that big a deal, but it's nice. Anyway, look for:
"We will help them without betrayal" before the Maribel.
"No, I can't." at Coordinate 136 (doesn't matter what you pick for the second one, but if you say you don't remember, it's funny and adorable. Just sayin.)
"It doesn't matter" in Ajna.
Also? AWESOME AND YAY to you playing this game. I am very much looking forward to your thoughts on it. <3
