House Party House Party - Stephanie's Story Walkthrough

Stephanie Guide for the House Party (Patch 10.2). So this is a bit preemptive, but 10.2 or later should be coming to Steam Early Access fairly soon and it seems like other players with Beta Access have been getting stumped at different points in this quest (I was too!) so I thought I'd provide a brief guide for her new story content.

Intro

Stephanie's quest can be started as early as the beginning of the game, which is where this guide will start. I'm only aware of a couple quests that conflict with Stephanie's quest:

Humiliating Ashley
Romancing Katherine

I don't think the completion of this quest will confict with you pursuing Rachel or inviting Vickie. There are multiple ways of going about this quest, this is simply the route that worked for me.

Game Start

Talk to Madison, say see you later.
Talk to Katherine, say Always a Pleasure.
Talk to Amy, say nice to meet you and see you later.
Talk to Stephanie.

Nice to Meet you.
How do you know Madison.
What do you think of Katherine.
Compliment her dancing.
Agree to find her Whip its.
Ask what a Whip it is.
Ask her what she does for work.
Ask if she's the cook.
Say it's good to get paid (There's a funny interaction with Derek, if he's in her vacinity).
Do not give her whip-it's - It will end the rest of this quest line. Wait until after the quest is complete.

Patrick

Introduce yourself to Patrick.
Ask him what you can do to help.
Retrieve the painkillers from the Master Bathroom (Behind the door).
This part may be time consuming. You need to give patrick the painkillers while he's near Stephanie. Not sure what the range is, I just waited until he was either talking to or dancing with Stephanie in the living room.
Give the painkillers to Patrick.
Say see you later.

Talk to Stephanie, she should comment on you helping Patrick.
Say there's more to it than that.
Ask her what she studies.
Ask her about pursuing a medical career.
Say see you later.

Amy should approach you about Stephanie and Katherine.

Katherine

Talk to Katherine.
Say you think we use need out of its intended purpose.
Ask why she's looking at her phone.
Say who could ever be mean to her.
Ask her if she would like a drink.
Talk to Katherine again.
Ask what kind of drink she likes.

Talk to Frank.
Say I'm totally sober.
Ask if he's going to guard the alcohol all night.
Ask what he thinks of Katherine.

Talk to Frank.

Go to the master bedroom.
Take the camera on the vanity next to the TV.
Go to the room with Brittany and the Laptop.
Take the SD card to the right of the laptop.
Open your inventory.
Scroll to the Camera and "Use With" the SD Card.
Go downstairs to the Garage.
Take the Cell Phone Jammer on the cabinet.

Ask why she's looking at her phone.
Say who could ever be mean to her.
Ask her if she would like a drink.
Talk to Katherine again.
Ask what kind of drink she likes.

Jamming

At this point, Katherine is more than likely outside by the Hot Tub. If she is in this location or any location that is populated follow the steps below. If she is in a room alone, skip to the next section.

Stand next to Katherine, Open your inventory, scroll to the Cell Phone Jammer, and turn it on.
It may take a moment, but Katherine should comment on the lack of service.
Follow Katherine until she is in a room with no one else in it (This may take a while).

Photography

Once you are in a room alone with Katherine, close the door and turn the jammer off if it is on (this is done the same way you turn it on).
Talk to Katherine.
Ask her to take a picture.
Talk to Katherine.
Ask her to take her top off.
Talk to Katherine.
Tell her this isn't what Frank had in mind when he said "Topless".
Talk to Katherine.
Tell her to try a pose.
Pick any pose.
Open your inventory and select the camera, take a picture.
Talk to Katherine.
Say let's take a break.
Return to Frank and give him the camera.
Open the cabinet to your right and take the Rum on the bottom row.

Emergency

Go to the Master Bedroom and enter the closet.
Take the "Clear Eyes" to your immediate right (it's a small white container).
Open your inventory and select the Rum, "Use With" Clear Eyes.
Return to Katherine.
Give her the Tampered Rum.
Talk to Katherine, she'll tell you to talk to her later.
Leave her vacinity.
In a few moments, she'll say she needs some fresh air.
Another few moments later she'll say she needs to use the restroom and run back inside.
Once she is in the bathroom, Talk to Stephanie.
Tell her Katherine is in trouble.
Select either option.
Follow Stephanie and listen to the conversation.
It may take Stephanie a long time, but she will run upstairs afterwards.
I'm not sure if this is automatic or not, but Amy may talk to you. If it doesn't trigger, you can talk to Amy, though I believe it's optional.
Go outside, turn right and then right again to the side of the house (Where Rachel's Events take place).
Take the fast food bag behind the AC unit, it's a flat brown bag.

Meltdown

Stephanie will be in the painting room at the top of the stairs.
Talk to Stephanie.
Give her the fast food bag.
Follow Stephanie back downstairs.
Listen to her conversation.
Agree to find the Gut Grip and Water.
Save your game!

This is where things can get tricky, at least for me, and there may be other options, but this is the way that worked for me.
Go to the Master Bathroom.
Right alongside the Toilet is the Gut Grip, take it (It's a small bottle).
By this time Stephanie should have returned to the Painting Room.
Go Downstairs and Knock on the bathroom door, ask where Stephanie is.
Go upstairs to the Painting Room, conversation should start as soon as you get close to Stephanie.
Ask what she's doing up here.
Say you still need to get water.
Say ok I'll get it.
Click on her again.
There should be an option to the take the bag, click it.
Say this needs to stop.
Screen should fade to black.
Listen to the rest of the conversation.

Special Training + Post Quest

Talk to Stephanie.
From here you'll now have the option to become intimate with Stephanie whenever you want!
Simply lead her into an empty room, close the door, and enjoy!

I don't believe you have the chance to get fully nude before the festivites begin. I haven't tried getting naked before she enters the room but it may be worth a try.
The fact that she follows you and doesn't require you to lock the door, actually makes her the easiest option for getting a condom from Frank.
You can still give her Whip it's and Alcohol after this quest.
You can still get her to dance topless and dance outside after this quest.
And you can still complete Brittany's quest line after the quest is complete.
Doing these things will not negate your ability to receive more training from Stephanie later.
