Jane had to ask if she could please sleep in a different room from them

Terezi gets some accommodations for her blindness, and she ABSOLUTELY abuses it to, for example, wander into restricted areas without getting in trouble

Another Anon suggested Terezi having a pet bearded dragon which is great

Vriska kinda gets detention a lot and Terezi bails her out

There’s not actually any Harry Potter lore for doppelgangers, so that’s what I’m calling him. 3rd year Dirk wanted to get more out of his school time, so he got into some highly forbidden dark magics to create a stand-in for himself. Initially the plan was to merge back together at the end of the year.

Just curious, why'd you put Jane as Slytherin? And sorry to ask, but who is Booboo?

If Gamzee wasn’t scary smart, he wouldn’t be nearly as effective a villain. Ravenclaws are known to be odd and ingenuitive. Putting him in Slytherin would be boring, and even at his most cunning he doesn’t have the kind of self-preservation instinct you expect in a Slytherin.

I put Jane in Slytherin because I think she’s absolutely ruthless; She DOES have problems making a decision in a crisis, but when she does choose, it’s absolutely her own success and survival first.
