Recently Vox and Valentino had a disagreement when Valentino had one of his perusal temper tantrums. It ended with Valentino managing to break Vox's screen leaving him pretty damaged

Vox was at his office looking pretty upset and mumbling to himself about what Valentino did to his face. He was thankful you were there to help him with the screen repair equipment by your side, but he was still on edge, with a scowl on his face

"Ungreatful rat...."
