On Aya you can talk to this Angaran woman selling various kinds of fruits native to their planet. If you choose to talk to her you can learn fruit isn’t exactly rare or scarce and yes, some can be expensive comparatively. But there is a reason for it. There is one fruit (I can’t remember the name) that isn’t meant to be used for everyday life. It’s function in Angaran society is to be shared among friends and family in celebration of something wonderful.
What that would be for them, I can’t guess. Maybe the joy of a birth? Joining of families? Marriage between individuals?
Wouldn’t it be absolutely sweet for Ryder to purchase one of these fruits once her and Jaal got serious?
It would mean the world to him. After he questions her if she knows what the fruit is used in Angaran culture, he’d yell Sara and engulf her in a soul-crushing embrace out of pure unfiltered joy, spinning her around the room in a dizzying fit as they laugh together. Jaal more so than Sara as he can’t contain himself. Not after this. I love you goes only so far and this… fruit symbolizes much more than that.
It is a physical representation of their love. A reason to celebrate.
