"This is one of several options to support Ellie when she is being bothered by some of Logan's
minions and Dylan acts like her boyfriend to keep the trash away from Ellie."
Logan is a Singular asshole who thinks with his dick.
He is an Alpha male for his group of buddies, and I see them as little more than his minions.
They are hardly a gang or organized as such, but in RL, I've run into these types of guys before - for example, a group of 4/5 guys with an obvious leader and I always saw them as minions and sycophants, waiting for the leader to decide what was or was not important.
His 'minions' would never hit on Ellie while she was with Logan.
Now that she is not (I've done everything I can to break up Ellie from Logan in my playthrough - not that I'll see meaningful story changes for years in RL), the minions feel free to take their shots.
Cheers!
