For us to have multiple option (the PC gith) is fine. You can roleplay i dunno, like being stolen as an egg and growing up away from Githyanki culture.
But the actual indoctrinated Githyanki should come up with better dialogue.
either straight up be super sus about us being the way we are... are we a githyanki? maybe we are a githzerai... she should be way harsher towards a githyanki that doesnt recognize/understand any githyanki tradition and basic knowledge than other races...
from my PC dialogue options not recognizing that laezel looks exactly like me... is weird. did i grow up in a place with no mirrors? mirrors dont exist from where i came from? neither water? have i ever seen my own reflection? why do i think laezel looks alien to me and i to her?
then some dialogue from Lae'zels part, especially like the "fleshy nose" one and the "you are as much alien to me as i am to you" were... awful.
