They may decide to go with it being Benji's door but its opened by someone else he had over when he thought Victor dumped him. After all they would need a full season out of it.
This is what I think will happen:
Victor went to Rahim.
Rahim and Victor tried to be together.
Victor was not feeling happy or happier despite of Rahim being nice.
Benji tries to move on with some other guy. But nothing works.
Something happened that needs them to work together - like get trapped in an elevator, locked in a room, etc. force them to confront each other's feeling. They ended up sleeping together.
Realizing this, Vic break off with Rahim.
The two came back together.
Until something happened in Texas, that would require Victor's family to move back to Texas, putting Victor and Benji's relationship at risk.
Season 4.
