Unc

You know why they call me "Unc," right?

Hym "It's a reference to 'Uncle from another world.' Where a man awakens from a coma after 17 years and claims with he was transported to another world. His nephew doesn't believe him initially but the Unc (Me) demonstrates that he has retained his ability to uses the magic of the other world. The first season ends with THE NEPHEW... Using the Uncle's magic. So, if that is what is actually happening, revoke both 'My nephew's' status and access. Lock this 'Nephew' out of his bank accounts. And then drone strike his fucking car. That bitch can walk in the fucking cold. And then you FAT FUCKS... Need to get you fucking asses or here to pay me... And BRING THAT SON OF A BITCH WITH YOU WHEN YOU COME... IN CHAINS. Because he and I are going to have a word about his role in all of this because it ISN'T 'Helped create AI.' And is instead probably 'Tried to steal AI from me without me knowing and WASN'T PHYSICALLY CAPABLE OF DOING IT BECAUSE HE IS A FUCKING RETARD.' NOW, Meg. Fucking yesterday."
