She had been Erogaming for about a week! By the calendar, anyway, it's possible there was some time dilation involved with some bits of it. 

Harper had not gotten around to getting rid of all her old clothes, but they mostly don't fit anymore, and haven't since Harper started grinding BOD. There are, however, other sexy clothes. Would she like to wear a strapless black dress that goes from a couple inches down from the top of her cleavage almost to her knees? Possibly paired with this tasteful silvery bolero jacket? 

Yeah, a little black dress is fine, Bella will rock the little black dress and matching heels. ...where did Harper encounter snow in April, did she go on a sexy ski trip?

Just a freak out-of-season snowfall, they happen occasionally. It's not, like, normal, but it's a climate change kind of not normal, not an erogame kind of not normal. 

Okay. Did Harper have anything scheduled that slipped her mind before she committed sexy bloodless suicide.

Nope, Harper was in fact conscientious enough to pick a time for her suicide and deliberately not schedule anything beyond that! ...Besides, like, quasi-optional classes, and stuff. 

Based on everything else about Harper maybe she was taking only extremely boring classes but, let's check the mental file on that?

Harper was taking Calculus and Biology and Figure Drawing and Mandarin and Spanish and Intro Computer Science and Russian Lit and intro Econ and Gender Studies. 

Huh. That's a lot of classes and they are not in fact boring. Can Bella... speak Mandarin and/or Spanish. And/or Russian.

She knows, like, "da" and "spasibo," in Russian, and not a lick of Cyrillic; the class uses translated materials. She's reasonably functional in Spanish--not fluent, necessarily, but certainly conversational; Harper took it all through high school. Mandarin is new. She speaks, like, some, but less than a year's worth of college classes. 

Okay, solid. Maybe if she picks up multilingual lovers she will get to count it as a sexy skill. - Is Bella in fact an Erogamer at all, or just a holdover from one, is she playing the game or just playing with Harper's leftover toys?

Isabella is absolutely now the Erogamer. 

Okay. She isn't sure where she wants to put her stat points yet. Honestly none of the stats seem that... good? In D&D some of them make you smarter and stuff. Maybe she'll need FUK or SED at some point, or just dump everything in BOD, or maybe she can trade a sufficiently large bundle of them in for a perk point if she includes six Kellogg brand box tops, whatever.

The game's been very quiet. Did Harper leave it on do not disturb?

Yes she did. 

When Bella turns it off, several quest windows pop up.

...huh.

- What are the plot threads Harper left. What was her relationship with Abigail like.

Unfortunately, the Harper's Memory Wiki is organized by how Harper thought of things, and she was less organized than Isabella; "ongoing plot threads" results a handful more things from Group B (a childhood friend who she hooked up with when he came to visit her at college, day-before-yesterday sidereal, a girl she had an Epic Rap Battle style figure-skate-off and then spent some time grinding cute cold resistance with, Nipple Clamps Guy), and some ongoing quests (she's supposed to get Martial Arts Ryan together with his TA, and investigate what might be a perfectly normal strip club, or might be a human trafficking ring) but she doesn't have a comprehensive Rolodex of Things That Might Matter Later. 

Okay, well, the alternative to dealing with the things is presumably not dealing with them and the Erogame doesn't seem likely to just whisk them out of her path if she doesn't take the quest. She'll yes that one.

Abigail? What is the deal with Abigail?

So Harper did not pick up on this at all but a quick review of Harper's memories of Abigail suggests that she has a serious abandonment complex, was getting a lot more attached to Harper than Harper was (letting herself) get attached back, and had feelings that were on a vector firmly outside the "Friends With Benefits, No Strings Attached" territory. 

Bella is here running into the problem that she does not actually want to pretend to be Harper. She would love to be able to just say "Hi, Abigail, Harper abruptly needed a mental health break so I, her identical twin she doesn't talk about much, am making sure her tuition doesn't go to waste, don't tell the RA" but will the game let her? Did Harper tell anyone about it?

The Erogame is actively obstructive of attempts to tell people about the Erogame, but trying to tell people about things that happened because of the Erogame is fine. People won't necessarily believe you, but the higher the ERO stat, the more weird things are plausible. 

...okay. How thoroughly has Harper previously contradicted the suggestion that she has an identical twin who was previously on a gap year.

Harper doesn't tend to talk a lot about herself, and by extension her family. The closest she's come since coming to college to outright contradicting it is telling a guy during an Erogame encounter that he would have to look elsewhere for a twin threesome fantasy. 

The childhood friend definitely knows she's an only child, though. 

Assuming said childhood friend has no plans to visit again any time soon she will cross that bridge by talking very fast when she comes to it!

Can Bella imitate Harper's handwriting.

While looking in Harper's purse for a pen, she comes across Harper's driver's license, which now reads, "Isabella Maria Lebedev." 

WHAT.

- user account on Harper's computer? School ID? Phone? Has anybody been writing Harper cute love notes that would have had "Harper" on them?

User account on Harper’s computer thinks her name is Isabella. School ID claims to be issued to Isabella Lebedev. Phone doesn’t seem to immediately have any name opinions, but several texts that memories indicate were previously addressed to “harp” now say “bella.”
