Mettaton fidgeted standing outside the door to Napstablook's private room. It wasn't like him to be nervous, but this situation called for being at least a little unnerved. It was still early on in their troupe's tour on the surface. That meant it was about time Mettaton came clean with Napstablook about something very important.
The robot knocked on the door before opening it to peek inside. The ghost turned to look at him from across the room where they had been floating in front of their computer.
"oh…Mettaton…"
Upon hearing his name Mettaton smiled and entered the room closing the door.
"Hello darling. How is our excellent music mixer doing?" It was stalling he knew but it felt necessary.
"oh…i'm fine… do you need anything?" The ghost drifted over a little, enough to keep a respective distance.
"Me? Oh, no, I just," Mettaton took a breath before continuing, "Napstablook." He could feel his resolve coming together. The next words had to be chosen with care. He didn't want his cousin to cry.
"…"
"Napstablook it's…me. Blooky, darling, I hope you at least remember your dear cousin?"
Mettaton waited until a look of realization appeared on the ghost's face. It was hard to see since Napstablook stayed relatively unexpressive, but he could see it. The time they spent together had never been lost to memory.
"I know no amount of apologies can make up for what I did. After our cousin left to become a dummy I told you I wouldn't leave. Yet, look at me. I did leave, and I left you so alone. Oh, Blooky, I'm the worst excuse for a cousin! I even waited until we got up to the surface to tell you all this!" Mettaton worked himself up into a fit of almost tears as he talked. What managed to catch him was the fact Napstablook cried before he could. "Blooky!"
"i…i figured it out," the ghost paused at sensing confusion and continued with, "oh…as you were talking i sort of figured it out… i remember you weren't really comfortable being incorporeal… being a robot you could make it look like you wanted… i'm not sure if you want to hear it but… i forgive you," explained Napstablook drifting closer to Mettaton. The robot felt himself washed over with joy and relief. He didn't expect to feel either.
"Blooky! I, what are those tears?"
"oh…i guess…they call them tears of joy?"
Mettaton let a short laugh escape before he wrapped arms around the ghost. He knew they'd phase through if they touched Napstablook so he was careful to make it look as if they were hugging.
"mettaton… i'm really happy to see you again even if you're a robot now."
"It's lovely to see you again as well! If anything tries to tear us apart again, so help me, I will come back to you! Dry those tears, baby."
