When they were all at the cafe the other BJ looked over at the counter where DG and his friend were working and said to Alex "he looks cute". Alex thought he was talking about DG and got irritated, especially when he went up and talked to DG. Later on Alex gets a box of sex toys from that guy and uses them on DG out of jealousy, this is what DG is sensing when he says "it feels like he's mad at me". Alex sees DG crying because he's scared and stops the sex to talk with DG about what DG had talked with that guy about because he'd been really jealous thinkin the guy was trying to get DG to come onto his show. That's why Alex keeps saying his dick is better than the toys and getting irritated about DG wanting the toys, he thinks DG might want to be fucked by the other guy if he likes the toys. DG says they just talked and wasn't hit on. If the "cute" one he was talking about wasn't DG, the only other person in his range of sight was DG's friend.
