well, both jenny and karkat had crashed at the house at different times in late february/early march, karen had been by at least once, maybe a second time to followup on a repair job. not sure how visible her relationship with renee was when most of their network conversations weren't public, but she might've been by once or twice, and she's gone now anyway. about the only other person who's easy to assume she might be friends with is violet. she talks to a lot of people but not many actually fall into that category.

there is public mention on the network of her being one of chilton's patients, and her association with greed has only been publicly mentioned once for someone who's actually looking for it in particular.

sorry i got caught up in reading threads while answering this.
