“Ziyal was posthumously referenced in a deleted scene from the start of sixth season installment “Resurrection”. In the scene, her paintings filled Kira’s quarters and Ziyal herself was briefly spoken about in a conversation between Kira and Jadzia Dax; when Dax observed Kira still missed Ziyal, Kira replied with an assurance she would “get over it.”“ - Taken from the Memory Alpha wiki
This is absolutely heartbreaking on multiple levels because at first it sounds like a really harsh thing to say, about the death of what’s basically her adoptive daughter. But then you remember that Kira that Kira has lost so many people during the war that she either has to get over it or risk never moving forward again.
But in that moment it still hurt and Kira wouldn’t have dismissed it like that if it hadn’t. It would’ve been such a poignant scene for her personal outlook. Part of me wonders whether she even ever processes those emotions like she should, or whether they end up perpetually buried because that’s not a war she’d be able to win. And poor fucking Ziyal is just, in that moment, another casualty.
