Do Lisa and David know each other outside?

[BlackOrWhite]

It seems like they were mates on the outside, David seems to speak to her like they've been friends for quite a long time. Anybody else think the same?

[Rodrigo2Win]

It's possible. But why would BB favour her, when she's the vilest one in there?

[Bombardier]

I'm struggling to think of one social circle that could possibly include these two characters. They're very, very different.

They maybe met at auditions. Many of them know each other that way.
