That Rachel was ever in love with Chloe. I remember i convinced myself it a lot when playing through it for the first time since i loved her character and the infuation that Chloe felt really smitted over to me the player, but replaying it now my mind has changed.
The kiss really made me fangirl back in the day, but after playing it now some years later i feel like it all is just one-sided from Chloe's side and Rachel had no problems kissing Chloe since she did care about Chloe and probably enjoyed the excitement being with Chloe gave her, but i feel like the two of them together was a fire that fizzled out fast.. Really fast. Which explains what happens in the original game.

Funnily enough i still ship Chloe so much more with Rachel to this day. I think Rachel is a really complex and interesting character. I just think Chloe deserved better
