Ok, so I'm trying to expand on my earlier post, and like I tried to articulate, I'm sure there are plot points I've forgotten and/or just didn't notice, but I think Sasha and Pandora are sus. I like both of them, Sasha's banter can get to be a bit to much (imo), but the way she has come on so hard and been supportive of making the mc happy while not putting out much, seems like she's trying to gain points (potentially). Meanwhile she's had access to the ships systems, however she has also been trying to teach/mentor the innocent girl (if that's how you're playing, I think). Idk, I feel like she's low enough on the "there's no way you would expect her" list and high enough of the capability list where she would a somewhat surprising antagonist. Likewise, I don't remember much about Pandora's backstory other than she showed up out of the blue trying to save her planet and entrusting the MC to help her in that endeavor. She instantly created a situation where the stakes are high, and trust is needed, which seems like a great way for the culprit to earn our trust. Idk, Paige raised Raegen as a suspect and honestly, I thought she was a pretty good darkhorse candidate too. Others have mentioned someone from the mc's past, like Lauren(?) and that idea would also be pretty surprising, especially because that would mean all of the girls on the ship were innocent. Well happy speculating I guess and feel free to address any errors, I'm looking forward to the next chapter.
