Being in an open relationship, they both enjoyed their right to hook up with other people, but with Pablo so far away and jealousy setting in, Sahar is beginning to rethink her decision.After a successful day working with Habitat for Humanity, the roommates go out to celebrate. Knight begins to see McKenzie in a different light, perhaps it's her bright, shining compassion, and thinks maybe she, not Jemmye, is the girl for him. But while McKenzie is willing to indulge Knight in some harmless flirting, she draws the line at that. With Knight putting the moves on McKenzie and McKenzie playing hard to get, Jemmye is left watching this all unfold before her eyes, and wonders that maybe Knight isn't the trustworthy, gentleman she once thought he was.With Sahar boiling from the Pablo Situation and the McKenzie/Knight/Jemmye Triangle brewing, she tells Knight he's being disrespectful.
