Pathologic 3: How to Complete the Theft Thought Quest – Clara Walkthrough
Learn how to complete the Theft thought quest in Pathologic 3 by finding Clara and manipulating your Mania level. This complete walkthrough covers all steps and important choices.
Investigating the Morphine Theft in Pathologic 3
Pathologic 3 loves throwing curveballs at you, and the Theft thought quest is a perfect example of the game’s more bizarre challenges. This isn’t your typical “go here, kill this, collect that” quest—instead, it requires you to understand the game’s unique mental state mechanics and use them in a way that probably won’t make sense until you’ve figured it out.
The setup is straightforward enough: Clara, the mysterious Changeling, is suspected of stealing morphine from the hospital. Your job as Daniil is to investigate and find out the truth. Simple, right?
Not even close.

Finding the Theft Thought on Day 5
The quest kicks off on Day 5 when the Theft thought appears in your mind map. Through dialogue with various NPCs, you’ll learn about the accusation against Clara—morphine has gone missing from the hospital, and all fingers point to her.
Naturally, your first instinct is to confront Clara directly and ask her about it. Unfortunately, Clara is about as cooperative as a cat being given a bath, and talking to her at the hospital leads absolutely nowhere.
She spooks easily and leaves, forcing you to track her down elsewhere. This is where the quest starts getting weird.
Tracking Clara to the Warehouse District
After your failed attempt at the hospital, Clara relocates to the pub in the Warehouse district. If you’ve been following our other guides, you might remember this area from saving Bad Grief on Day 4—it’s the criminal underworld’s stomping grounds.
When you find Clara at the pub, you’d think you could finally have a proper conversation with her. You’d be wrong.
Trying to talk to Clara here initially leads to another frustrating dead end. Even worse, these attempts will start spiking Daniil’s Mania level significantly. If you’re not prepared for this, it can throw your entire mental state balance out of whack.
The Key to Talking to Clara: Understanding Her Nature
Here’s where things get interesting, and where the game expects you to think outside the box. If you talk to the brothers at the bar in the pub, they’ll drop a crucial hint about Clara’s nature:
Clara reflects the mood state of whoever is talking to her.
This is the key to the entire quest. Clara isn’t being deliberately difficult (well, maybe a little)—she literally operates on a different wavelength depending on your mental state. And to get her to actually engage with you about the morphine theft, you need to be in a very specific mental state yourself.
Specifically, you need to be at full Mania.
How to Max Out Your Mania Level
Now here’s the beautifully absurd part of this quest: to raise your Mania to maximum, you need to keep talking to Clara over and over again, even though each conversation is infuriating and goes nowhere.
Each time you attempt to speak with her while your Mania isn’t maxed out, she’ll give you the same frustrating non-conversation that spikes Daniil’s Mania even higher. It’s maddening (pun absolutely intended), but that’s exactly the point.
The Process:
- Talk to Clara at the pub
- She gives you a circular, unhelpful response
- Your Mania increases
- Repeat until Mania bar is completely full
- Now you can actually discuss the morphine theft with her
It’s one of those game mechanics that feels intentionally designed to test your patience—very on-brand for Pathologic 3.
Critical Preparation: Stock Up on Apathy-Inducing Items
Before you commit to this quest, here’s some vital advice: bring Apathy-inducing drugs with you.
Why? Because you’re about to intentionally crank your Mania to maximum, and once this quest is done, you’ll need to bring it back down to manageable levels. Running around with maxed-out Mania for the rest of Day 5 is a recipe for disaster.
The Warehouse district has very few interactable objects that reduce Mania naturally, so you can’t count on finding relief in the environment. You need to come prepared with your own supplies.
Stock up on items that induce Apathy before heading to the pub. Trust me on this—future you will be grateful.

The Conversation With Clara: What Actually Happens
Once your Mania is maxed out and you can finally have a proper conversation with Clara, she’ll actually discuss the morphine theft and explain her reasoning behind it.
The specific dialogue choices you make during this conversation aren’t required to complete the quest—you’ll get credit for finishing it regardless of what you say. However, this is one of those branching narrative moments that Pathologic 3 is famous for.
Why Your Choices Matter
The decisions you make here may affect Clara’s relationship with her adoptive mother and potentially influence events later in the game. The game doesn’t immediately show you the consequences, but this is definitely an interaction worth noting for future reference.
This is classic Pathologic storytelling—your choices ripple forward in ways that might not become clear until much later. Take your time with this conversation and think about what kind of outcome you want for Clara.

After the Quest: Managing Your Mental State
Once you’ve completed the conversation and the quest is finished, your immediate priority should be reducing your Mania back to safe levels.
Use those Apathy-inducing items you (hopefully) brought with you. If you didn’t bring any, you’ll need to either:
- Fast-travel back to an area with Apathy-inducing interactable objects
- Visit a merchant and buy the necessary items
- Carefully manage your actions to avoid Mania-related consequences
High Mania affects Daniil’s perception and can lead to some seriously problematic situations if left unchecked. Don’t let it linger.

Why This Quest Is So Weird (And Why That’s Great)
The Theft thought quest perfectly encapsulates what makes Pathologic 3 such a unique experience. Most games would handle a theft investigation with simple dialogue trees or maybe a stealth section.
Pathologic 3 instead asks: “What if the person you need to talk to literally operates on a different mental wavelength than you, and you need to deliberately drive yourself into a manic state just to communicate with them?”
It’s bizarre, it’s frustrating, and it’s absolutely brilliant. The quest forces you to engage with the game’s mental state mechanics in a creative way while also reinforcing Clara’s nature as someone fundamentally different from the other characters.
Plus, there’s something darkly humorous about intentionally aggravating yourself through repeated failed conversations just to unlock the ability to have an actual conversation. It’s the kind of absurdist gameplay that stays with you.
Frequently Asked Questions
Do I have to complete this quest to finish the game?
The Theft thought quest is not mandatory for completing the main storyline, but it does provide important character development for Clara and may influence later events. If you’re going for a completionist playthrough or want to see all possible story branches, it’s worth doing.
What happens if I can’t get my Mania to maximum?
If you keep talking to Clara repeatedly at the pub, your Mania will eventually reach maximum—it’s basically guaranteed. Each failed conversation gives you a significant Mania boost. Just keep trying to talk to her, and you’ll get there. If your Mania is somehow resisting the increase, make sure you’re actually in the pub talking to Clara specifically, not just standing near her.
Can I complete this quest on a different day?
The Theft thought appears on Day 5, and that’s when the quest becomes available. While the game’s time travel mechanics theoretically allow for flexibility, it’s best to handle this quest on Day 5 as intended to avoid potential complications with the storyline.
What’s the best Apathy-inducing item to bring?
Any consumable item that specifically lists Apathy as an effect will work. The exact “best” choice depends on what you have available in your inventory and what you can afford from merchants. Generally, bring at least 2-3 doses to be safe—enough to bring your Mania from maximum back down to normal levels without running out.
The Theft thought quest is one of those wonderfully strange Pathologic moments where the solution feels completely counterintuitive until you understand the game’s internal logic. Intentionally maxing out your Mania to communicate with someone who mirrors your mental state? That’s the kind of creative problem-solving this series is built on.
Come prepared with Apathy-inducing items, be ready to have the same frustrating conversation multiple times, and pay attention to your dialogue choices with Clara—they might matter more than you think.
And remember: in a town where reality itself is questionable and a plague is turning everything upside down, sometimes getting answers means meeting people where they are—even if “where they are” is a state of complete mania.
