I'm going to guess when you split the juju's you'll go back to normal.
Since caliborn has a crowbar to pull them apart.
But yeah, dirk is kinda being a jerk, but he's super stressed as of current.
His boyfriend is ignoring him, he had to deal with AR blocking roxy from him, and now Arquiuusprite and the muscle touching.
He's fed up, and tired of all this bullshit, and then what happens? Three of his best friends completely altered and changed from who they are.
No wonder he's just snapped and was whatever when roxy said all of that.
Some people say if you're super happy you go trickster and when you get really depressed grimdark.
Yes grimdark dirk.
