Mettaton –
– First and foremost he’s going to try and keep you out of the camera eye of the paparazzi if he knows you don’t feel comfortable with it. Monster or human, they can be complete savages, darling, and some of them will stop at nothing to get their picture. It’s the life of a star, sweetheart, but you don’t have to be burnt out by it.
– If he hears someone saying unpleasant things about/to you, he’ll be over there before you can say “fabulous”, and he is not happy at all. He will be glaring down at whoever upset you with a small, irritated twitch, and an overly sickening sweet voice asking “Would you like to repeat that to me, darling?” This usually intimidates most people enough to leave.
– If the situation starts to escalate, he’s going to whisk you behind him with a flourish, but he’s going to enjoy the drama that ensues. After all, it’s what he’s best at, right?
