Can we take a moment to imagine if Todd Howard had allowed us to have two companions at once. Like, they could interact and both have comments on Sole’s actions, and then there’s a possibility they’ll have random arguments if they don’t get along. Also, if they REALLY don’t like each other, one of them might get a [ _____ Disliked That] notification upon requesting the other companion to join them.
They could also comment on the other companion’s affinity quests/approval speeches.
But some of these have the potential to be HILARIOUS while others could be kind of sad, too.
Danse, when Sole has Nick to follow them as well: I can’t believe you’re actually going to make me travel along side this… Thing. But if you insist.
Nick: Trust me, pal, I’m not any happier about this arrangement than you are.
X6-88, when Sole has Deacon to join them: I do not agree with your decision to allow this man to accompany us, sir/ma'am. I don’t know him, and I cannot be sure that he is a trustworthy ally.
Deacon: Me? Untrustworthy? Please. I’m the most honest guy you’ll ever meet!
Strong, with practically every companion: Why human bring along other puny human? Strong the only protection this human need!
MacCready, upon hearing Deacon’s story about Barbara during his third approval speech: Da— I mean, crap— I… I’m sorry. I know how that feels…
Hancock, when hearing Cait’s story about her chem addiction: Hey, sister, I like the high as much as anyone, but good on you for knowing when it’s time to quit. Can’t always speak for myself on that one…
Curie, when a synth: Monsieur Codsworth, have you ever considered the possibility of becoming a synth, as well? It is quite the experience!
Codsworth: The idea has never much crossed my mind, Miss Curie, although I daresay it does sound rather intriguing! However, I doubt that me becoming more human-like would be very beneficial to my service to sir/mum. Garden work is much more difficult with only two hands, you know!
Piper: Yanno, Garvey, I’ve had this idea for an article for a while now: “Hope for the future from the perspective of a Minuteman!” Whadda ya think? I’m sure the residents of the Commonwealth would eat that up!
Preston: *chuckle* Interesting idea, Piper. I’d be happy to give an interview later when we aren’t on the road.
Cait, when Sole has Dogmeat follow them: So we’re letting your mutt tag along, eh? Alright, as long as he doesn’t get in me way, we’ll be fine.
Strong, during MacCready’s story about Lucy being killed by Ferals: Strong smash ALL stupid ghouls for Mack-Ree-Dee!
Piper, when Nick is confessing that he doesn’t feel like he really matters since he’s just a copy of another man’s personality: Nicky, you’re a better person than most people in Diamond City! You’re one of the only people who even bothers to give me the time of the day… You’re a good man, don’t be so hard on yourself.
And then don’t get me STARTED on the companions reacting to random NPCs saying rude/insulting things to other companions like Nick or Hancock. Even better, Nick and Hancock BOTH snapping back at a rude NPC. The combined sass would be legendary.
NPC, snarkily at Nick: Hey! I can see this Protectron’s brain!
Nick: Protectron? *grumbles* That’s a new one…
Hancock, to the NPC: At least he has a brain. Guess the same can’t be said about you, though, can it?
Curie, when a NPC says something about Hancock or Nick: *gasp* How rude! Surely Monsieur Valentine/Hancock has done nothing to deserve such hostility!
NPC, to Hancock: Ugh, it’s hideous.
Hancock: You’d be the expert.
Nick, to the NPC: *irritated* Ever looked in a mirror, pal? You aren’t exactly pleasing to the opticals, either.
Cait, to the NPC: Oh, go to hell, the lot of ya! Don'tcha have anythin’ better to do with your miserable life?
Strong, to NPC: Humans talk too much! Strong smash tiny annoying human!
Piper, angrily: Hey, buddy! You wanna be in the next headline for Publick Occurances? It’s called “Biggest Douche Bag In The Commonwealth!”
There’s literally so much more I could add here but I think you all get the gist. It would be a lot of work and probably wouldn’t happen but THIS WOULD BE SO FREAKING AMAZING IF IT WAS IN GAME! Feel free to add more ideas!
