When Susan’s implant gets activated and she grabs Finn and says “target acquired” it’s because that was her original mission as revealed in the Islands mini series. I hadn’t made the connection until my, like, 25-30th watch or so lol. I guess I just assumed it was because he’s the only other human around. Did everyone already know this and I’m just super slow?

Edit: forgot to mention the episode, its Preboot in S8
