Fallout 4 Curie Likes: Why This French Robot Is The Hardest Companion To Please

You’ve probably spent hours wandering the Commonwealth with a dog, a cynical detective, or a super mutant who complains about everything. But then you find Vault 81. Deep in a secret hole where science went horribly wrong, you meet Curie. She's a Miss Handy with a thick French accent and a brain the size of a vertibird. She’s charming. She’s naive. Honestly, she's also one of the pickiest companions in the entire game. If you're looking for the lowdown on Fallout 4 Curie likes, you need to realize one thing right away: she isn't like Cait or Hancock. You can't just pick locks and do drugs to make her love you.

Curie is a woman—well, a robot, then a synth—of science.

She wants to save the world. Not through violence, but through a microscope. This makes her approval rating a bit of a nightmare if you’re playing as a morally grey mercenary. If you want to reach that sweet "Combat Medic" perk, you're going to have to play the hero. Or at least act like one when she’s looking.

The Moral Compass of a Research Assistant

Curie’s personality is built on the "Contagions" project. She’s been stuck in a box for 200 years trying to cure every disease known to man. When she finally steps out into the wasteland, she’s looking for progress.

When people search for Fallout 4 Curie likes, they usually expect a simple list. It's not that easy because her "likes" are tied to specific dialogue choices and world interactions that reflect kindness. She absolutely loves it when you choose the "nice" or "supportive" dialogue options. If a settler asks for help and you say "I'll do it for free," Curie’s heart (or processor) skips a beat. She’s one of the few companions who genuinely appreciates altruism.

But here is where it gets tricky.

She hates it when you're mean. Obviously. But she also hates it when you're greedy. If you negotiate for more caps during a quest, expect a "Curie disliked that" notification to pop up on the top left of your screen. It feels like a slap in the face when you're just trying to afford more .45 rounds. She views the pursuit of money as a distraction from the pursuit of knowledge.

Helping the Little Guy

If you want to farm affinity with Curie, go to Diamond City or Goodneighbor and just start talking to people. See a beggar? Give them a Nuka-Cola. See a farm under attack? Save it. She reacts positively to almost every Minutemen quest because the Minutemen are, fundamentally, about rebuilding society.

There is a specific interaction with the Vault-Tec Rep in Goodneighbor. If you've played the game, you know the guy. He's been a ghoul for two centuries and he's miserable. If you tell him to go to Sanctuary and give him a new lease on life, Curie loves it. It’s these small, human moments that move the needle for her.

Technical Quirks and the "Science" Bonus

Curie isn't just a fan of being a Boy Scout. She’s a nerd.

Because she’s a scientist, she responds well to technical solutions. If a quest gives you the option to fix a machine or use your Intelligence stat to solve a problem, take it. She respects the brain over the brawn. This is actually a great way to build affinity if you’re playing a high-INT build.

Interestingly, she has some very specific triggers:

• Healing Dogmeat: This is the most famous "cheese" for Curie. If Dogmeat gets downed in combat and you use a Stimpak on him while Curie is your active companion, she likes it. Every. Single. Time.
• Donating Items: Giving items to people in need, like the various "Give me water" NPCs, is a huge boost.
• The Brotherhood of Steel: This is a mixed bag. She likes the technology, but she's skeptical of the militarism. However, completing certain "recovery" quests for the Scribes can sometimes trigger positive reactions.

The Synth Transition: Everything Changes (Sort Of)

You can't talk about Fallout 4 Curie likes without talking about "Emergent Behavior." That’s her personal quest. Once you hit 250 affinity, she’ll tell you she feels limited by her Miss Handy body. She wants to be a human. Or, as close as she can get.

You take her to Dr. Amari at the Memory Den. You put her in a synth body. Suddenly, Curie is a different beast.

Mechanically, her combat style changes. She goes from a floating laser-bot to a glass cannon with a laser rifle. But her likes stay mostly the same. She still wants you to be the savior of the Commonwealth. The funny thing is, once she’s a synth, she starts experiencing "human" emotions like sneezing or feeling "fuzzy" inside. Your dialogue choices during these moments are critical. Be supportive. Don't tell her she’s just a machine. If you treat her like a person, her affinity will skyrocket.

What to Avoid Like the Plague

If you want to keep Curie happy, you have to leave your inner jerk at the door. She is arguably the most "Lawful Good" companion in the game, perhaps even more so than Preston Garvey.

1. Don't steal. Seriously. Even if it’s a cool piece of legendary armor in a chest that nobody is looking at. If the text is red, don't touch it.
2. No Chem use. She thinks drugs are a waste of biological potential. If you pop a Psycho or a Jet, she’s going to judge you. Hard.
3. No Murder. This seems obvious, but even killing "neutral" NPCs or being overly aggressive in dialogue will tank your relationship.
4. Synths and Ghouls. Curie is a scientist; she doesn't care about your DNA. If you are bigoted toward Synths or Ghouls, she will despise it. She views them as biological or technological marvels, not monsters.

The Secret to Maxing Her Out Fast

If you’re tired of the slow crawl, there’s a strategy. It involves the Brotherhood of Steel and the Railroad. Because Curie loves "helpful" acts, you can cycle through the repeatable "Learning Curve" or "Feeding the Troops" quests (though be careful with the latter, as coercing farmers is a "dislike").

The real MVP of affinity farming is the "Investigative" dialogue.

In almost every major quest line—The Silver Shroud, for example—you have the option to ask questions before accepting the job. Curie likes it when you seek information. She likes it even more when you finish the quest without unnecessary bloodshed. If you can talk a boss down instead of blowing their head off, do it.

The Romance Factor

Yes, you can romance Curie. It’s a bit weird if you think too hard about the fact that she was a robot five minutes ago, but hey, it's the apocalypse. Once you hit max affinity and finish her quest, you get the Combat Medic perk. This is one of the best perks in the game. If your health drops below 10%, you automatically heal 100 HP once per day. It’s a literal lifesaver.

To get there, you just need to keep being the "good guy."

It’s actually a refreshing way to play Fallout 4. Most players fall into the "sarcastic" or "mercenary" roles because they're fun. But playing for Curie forces you to see the Commonwealth through her eyes—as a place that can actually be fixed if everyone just stopped shooting each other for five seconds.

Actionable Steps for Your Next Session

If you’re loading up your save right now to go find her, here is exactly what you should do to maximize your time.

First, head to Vault 81. You’ll need three fusion cores to get in (or a high charisma check). Complete the "Hole in the Wall" quest. Make sure you give the cure to Austin. If you keep the cure for yourself, Curie will still join you, but you start off on the wrong foot, and honestly, it’s just a mean thing to do to a kid.

Once she’s with you, head to the nearest settlement that needs help. Do three or four "Radiant" quests for the Minutemen. Every time you accept the quest and say "I'll help," you'll see that "Curie liked that" message.

Keep a stack of Stimpaks. Find a group of Raiders, let Dogmeat take the brunt of the damage (sorry, buddy), and then stim him back up. It’s a bit manipulative, but science requires sacrifices.

Finally, get to the Memory Den as soon as the quest triggers. Her synth form is much easier to manage in terms of gear and equipment, and it opens up the final tiers of her affinity. Just remember: no stealing, no drugs, and keep the sarcasm to a minimum.

Treat her like the brilliant scientist she is, and you'll have the most loyal (and helpful) companion in the wasteland.

Next Steps for Success:

1. Check your current affinity level by opening the console and clicking on her (type getav CA_affinity), or just gauge her dialogue—if she’s talking about her research, you’re doing well.
2. Clear out your inventory of stolen goods before traveling with her to avoid accidental "dislikes" when you drop or move items.
3. Prioritize the "Hole in the Wall" quest early in your playthrough so you can benefit from her perk for the majority of the game.
4. Swap your armor to something with high Charisma stats before talking to NPCs, ensuring you can hit those "Peaceful" dialogue checks she loves so much.
