Aww Issi.
I know, it's horrible.
It's true, they don't leave any ship unscathed...even my Frary. I don't even think Lorcisse is safe.
But, that doesn't mean it's completely hopeless. Greer and Castleroy ended up together... and who knows where Cleith and everyone else will end up by the series finale. That's why we have to see it through all the way.
