OBSERVATION: All four are FUCKED up in the head.
Layla sitting with her bottle and doesn't give a shit. Based on her demeanor and body posture, she has low self-esteem, not a caring person and with bottle in hand, feels her best features are the 3 holes available for any guy to use. She might be good to look at naked but she wouldn't be a reliable friend.
Both dudes slightly care about the brunette who probably is drunk, stoned or both (I doubt she's bipolar). Eric is there just for fucking. In the few days I've seen them interact, I see no deep down passion (even though VHTV says they've been together a for awhile). Both Eric and Layla definitely estranged from their mom/dad.
With other channels, I have interest besides their fucking on what kind of people they are. With this particular apartment, I just wanna see her get fucked a few more times (or at least until he achieves a boner to give her a good fuck) before I get bored.
