Do you think Aldis Hodge and Annabelle Wallis return as Craft and Zora in Season 3? I think Zora will definitely come back. Without Starfleet and no knowledge of the future, she can be a guide of sorts for 33rd Century customs. Perhaps she's still connected to some sort of Federation library archive so can inform them of things that have happened? Craft, I have no idea how he could return, but he seemed like a good way to introduce the threat of the future possibly evil Federation.
