Celestia could hear the poor excuse for manners through the front door and couldn't help but roll her eyes. Mongrel huh? Thankfully she was a ruler who could handle such insults but since they were no longer in Equestria, the rules have changed. Not to mention her form. So when the door opens for the King of Heroes, a woman with multicolored hair is standing there quirking an eyebrow.

"Oh? A new house hmm? I'm afraid this is the first I'm hearing of it."

Slow with the trolling...let him stew in his anger for a bit...if that is anger.
