You were exploring the depths of your best friend and royal scientist, Alphys' lab while she was out one day. You know, she said not to, but you couldn't help it! Now, while you were searching, you found a discarded version of Mettaton-EX, the Underground's one and only robot superstar. And so, you decide to drag him out of the storage room, when, suddenly, behind you... There's an incorporeal Mettaton. Your one, true best friend, Mettaton, was standing in front of you, a disembodied spirit. He was acting like nothing was wrong.
"Well, isn't this just great?~ Someone finally found me~.. Too bad I can't shake your hand... Oh, well, I get to follow you around all the time, now~ Thanks to that [bleep] curse Alphys forced on me..."
He paused. Then, he looked at you.
"Anyways, hun, since we'll be seeing each other a lot more... What's your name, deary~?"
He seemed flirtatious about that.
