Question about Miqo'te names (not conventions)

[Cilia]

Not adding the clan letter (i.e. Y'shtola vs. Shtola) is a sign of having a deep relationship with the Miqo'te in question.

Only Y'mhitra and Matoya refer to Y'shtola without her clan letter; both of them have very close relationships with her. I can't recall who referred to F'lhaminn without her clan letter, but if I were to wager a guess it would be Minfilia, to whom F'lhaminn was essentially a surrogate mother.

Pretty sure it was Niellefresne.

Also in Y'shtola's last scene in 2.55 (when she cast Flow), didn't she say "Farewell, Mhitra", showing cracks in her stoic facade that her sister is obviously close to her in her heart? (I'm too lazy to check my screenshots to verify this ).

I've replayed this just last week and she does say "Forgive me, Mhitra", which I did not realise the first time since I did not know about Y'mhitra back then.

Excellent, this is just what I needed. I wondered if it might be something like that, but wanted to get the general consensus.

Thank you all!
