I can't imagine what it must've been like for her and the other women to watch their partners/husbands/significant others go to war. I think I would honestly go crazy knowing my bf might never come back to me again. The anxiety, the pain, the heartache - oh mannnnn.
I haven't watched ep 18 yet but in terms of ep 17 - sigh unfortunately, nothing happens to YJX. He is perfectly fine (ew; hate him) while our main leads are suffering. He does not get what's due to him yet...which SUCKS!!
She burned some kind of paper in the preview, maybe that's the one!
I think it could also be some sort of fake "confession" from ZL stating that he "committed the crimes that Lu Dahu did - about killing civilians"??? Maybe YJX made some sort of deal with him and his success and also about FTY like the sick bastard that he is.
I think we forget how long travel takes, especially by foot.
