This might be a bit of a niche crossover but hear me out; Project Hail Mary and the Lifeline game series. More specifically I’m thinking that Grace and Rocky are the ones who rescue Taylor at the end of the first game (it’s the only one I’ve actually played, I know I know! I should play the other ones too, I’m working on it). Taylor is literally on a moon in Tau Ceti’s solar system! And think about how interesting their dynamics could be! Taylor being vary of Rocky at first bc of their experience with the Green, Grace going into teacher mode to comfort Taylor (I imagine them being like 19-21 years old), them all bonding over science together (Taylor does science right? I’m hope I’m not misremembering that, it’s been awhile since I played Lifeline), etc. I’m rambling and my thoughts are very incoherent but you see the vision right?????
