Things I've found out about Jaal through party banter:
1. He can’t eat grape flavored candy/drinks/etc. because the methyl anthranilate used to create grape flavoring burns
2. Angara are immune to the capsaicin in peppers
3. He is 27 years old (on certain planets he’s older/younger, apparently, according to him. But his standard age is 27)
4. He hates the heat.
5. “Shalom” is his favorite human greeting
I will reblog this and add to it as I find out more lmao
