I had a look at Stargaze's Fellowships and I'm thinking that Skobeloff would be a good fit for this one.

___ showed you that the Darkness lingers everywhere. Tell them what Darkness you see in them, and take a Friendship Gem from them.

Skobeloff can be pretty power hungry at times. If she comes to him for help with pranks fairly often, Stargaze might notice this hunger for power in the form of Skobeloff's plans for humiliating the bullies also tending to leave him with some form of leverage over their targets.
