So, I really haven’t watched regularly since Ziva left. Emily and all others weren’t working for me after a handful of episodes. I liked Ziva 70% of the time over her run, so I am a fan.
It feels like they’ve made a point of Emily being the driver of wanting to know more about Ziva. That to me, after all these years away, means they value Emily as a character. They aren’t looking to replace her.
I think there will be a bonding moment next season meant to confirm fandom from Ziva to Emily.
regardless, I don’t see Ziva back full time , I don’t see Emily being gone. My optimistic view/hope is that Ziva can repair relationships/be quick mentor to Emily in the 1 or two episodes she’s around, and we know she and her family (Tony/Talia). are safe even if we don’t see them.
And if it leads to popping up here/there in an episode going forward, I’d love it, but would not need/expect it.
