Rio’s black Heart

I had to do something that I did not want to do, even though it was my job. And it hurt them.

This extremely awkward conversation with Avad, who is trying to court her (a reminder that people are romantically interested in her)

Zo and Varl's relationship - I personally don't think her reaction was necessarily jealousy, just her being confronted with the possibility of falling for someone for the first time (after years of living as an outcast)

Finding out about Elizabeth's past relationship with Tilda, and that she wasn't as untouchable as she thought her to be

And finally, her conversation with Talanah at Barren Light about first love (or crush) - all but predicting BS

If, when they met, Aloy represents the sky (aka crashing from her sunwing)

And Seyka represents the sea…
