ksenia’s name was left out of the release but I really think that was just for keeping her return quiet.
Mostly because I wouldn’t be even a little bit surprised if he saw her in the first 3 episodes. Not as Kenzi, but as Angel. The sifter friend of Dyson’s who has the other hellskore (no idea if I spelled that right). Most likely, that will be how they keep Ksenia in the season until they figure out kenzi’s return.
This theory is legit the only reason I am not losing my mind.
