He's literally min-maxing his parasocial relationships holy shitBut going out of his way to privately tell someone he loves them for tattooing his fucking brand logo onto their body and to ignore the people pointing out how fucking absurd that is? That's not the usual opportunistic grifting he does. That's actually grooming a mentally unfit person - because let's be real, if you tattoo a fucking logo of your favorite brand to your body, you need some kind of handler because you clearly would be too willing to buy a bridge I have for sale. And he knew it would get screencapped and become seen by his other fans - he wants them to see how "good" he is in private too, likely in hopes that they set up opportunities for him to continue to "privately" praise them for showing more and more zealous behavior. Dream is now not only clearly one of these whores, he's honestly becoming more vile than them. He's going from grifter to full-on wannabe cult leader.
I can just imagine a parent who has the balls to call this shit out to hunt 'ol fattie down, hogtie him, and plant a poker on his ass for being all creepy with his daughter. Then again, a responsible parent would be cognizant of what weird shit their teen is going through and would nip that in the bud quick (or at the very least give them a good spanking)
