I hope her little brother Zeke plays a bigger role this time around in some form and that we see more of him coming to Keira's aid and in general being supportive the way he is rn. After her, he's one of my fave characters because he loves Keira just the way she is. in the original timeline despite her seemingly cold personality and in the current one where she's more open. I think thats a sweet sibling relationship.
Oh on that note. If we do get to see what happened after Keira died in the original timeline, I do hope we get to see more of Zeke there too. He must have been absolutely distraught about it. Would be nice if he was the one who told their dad off in that timeline on Keira's behalf.
