RE: BIANCA'S BUTT
The more I think about the Bianca ass-grab the more it annoys me. Because you can't be a DiK in a Jill playthrough, meaning you can't touch Sarah and Mel's asses in their photo. You can, however, grab Bianca's while Jill is standing right there. The game is actively blocking you from making "bad" choices, but it's also creating new "bad" choices you CAN choose to make. When a game about making choices and dealing with consequences starts gatekeeping which mistakes you can and can't decide to make, that's a bad sign.
RE: MYSTERY BLUE-EYED GIRL
If the blue-eyed girl is Ellie, that's really dumb. Bringing back the Swyper girls in minor roles is cool: I like Misha being around, and Ida showing as Santa was great. But the blue-eyed girl is a legitimate mystery that has to span at least two episodes, given that it was introduced here but not yet answered. That's too much hype for a girl much of the player base will have forgotten existed, and who likely won't amount to more than a one-off shag.
It's more likely, IMO, that this is a new character and the reveal will work the other way. A new character of some importance will be revealed, and we (the player, if not the MC) will recognize their eyes and that we've met them before.
