This page introduces a character who has been mentioned in past pages, but has never been shown until now: Rita, Chelsea’s foster mom. As can be assumed since she’s been mostly absent or out-of-sight before this page, the two don’t exactly share a very close familial relationship. Instead, Rita basically acts as a room and board, treating Chelsea more like a tenant than a potential daughter.
Another reason why Chelsea has needed Pearl all this time, which will make losing her all the more difficult.
