I mean I get it, he's an adorable synth with what's gotta be one of the more complex backstories and questlines in game, along with how many missions he can add to, including Far Harbor which I think fitably should be called Valentine's DLC, and the cutest lines and thoughts and just being him in general, but anyway, I like - well, love - the best friend aspect of the highest affinity with Nick. It makes me think of those cliche movies where the outcast young adult is friends with the middle-aged wise man of the town and they go on adventures and learn life lessons and what not. I don't know it just feels like his whole story and his experiences that you go through with him don't seem like they would work as a backing to a romance? It really does feel like a best friend aspect, more than any other companion in the game (I think Piper would also fit on the list, something about how she treats the SS makes me think of a great friendship as well). Obviously it feels like a BFFs type companion storyline, because that's what it is down to base coding lol, but even then, I base my head canons and AUs off of the experiences I have in game, so it might just be weird for me to change something that already exists... Which I guess is why it's called and Alternate Universe lol
