Cryo gets it!
1. My dance moves are famous on many worlds. - His dance is awesome and adorable.
2. I assure you, ladies, it's just a nickname! - His name is QUICKIE
3. I don't quite know why I'm with such inferior people though. - His party is made up of Inferians.
4. Especially when I could be hanging out with angels, metaphorically speaking. - And one Celestian.
5. In fact, my master is one of those "celestial people". - More direct hint at Meredy, plus the WORD Celestial.
6. My master may sound pretty stupid when translated... at all, but if you hear/read her in her original tongue, she's quite well spoken! - Meredy sounds pretty stupid at all times. Even when you get to her home planet and are supposedly listening to her in her language through a translator. However, if you translate the blocks of Celestian text she speaks, she's actually pretty well spoken and intelligent!
