Sam and Zoe had a certain spark despite the age-gap. They somehow made it work. I am quite annoyed at Zoe being killed off in the sequel . I would rather Sam fall in love with a doppelganger Summer than crazy Holly who by ep 9, seems to have no chemistry with Sam. Maybe they will have good scenes later but now, I don’t want Holly to end up with either Sam or Jayden. I keep thinking Holly might be better paired with the younger pilots.
