How did Lisa and Ray ended up living together?

[GARFIELDKOOL]

I just started watching Sister, Sister consistantly in the mornings. I know twins were separated at birth, but I guess I missed the storyline on how Lisa and Ray ended up sharing a house. I know they were not romantically involved. How could two people who are way different (personality wise) live together?

In the pilot after the twins meet for the 1st time not realizing the other existed Ray & Lisa let the twins get to know each other. I think Lisa lost her job and because of that Ray let Lisa & Tamara move in with him and Tia. Plus the girls became so close that they wanted to keep them together. If I remember correctly.

^ Yeah, Lisa gave up her apartment because she was originally going to take a job in St. Louis. Then Tamera suggested that Tia and Lisa move into the Campbell house, which they did at the last minute.
