HIV storyline?
When Deran and Adrian were sitting on the beach Adrian mentioned his ex fling being at the doctor or hospital because he has an infection - can't remember if it was lungs, liver, kidney...Later when Deran shows up at Adrian's, Adrian tells Deran that he doesn't feel the same way. That's quite the turnaround. I know we can read into it that Adrian is done being used and having a relationship that's one-sided but is it possible the ex found out he has HIV, told Adrian, and now Adrian is trying to protect Deran?
Not sure if this is even a possibility but throwing it out there to see what you think.
