It was actually Mettaton she was talking about.

"The person who warned us about you..."

"Offered us a LOT of money for your SOUL." (It's mentioned that MTT could be rich, but not really important.)

"They had such a sweet smile~ and... ahuhu~" (Reffering to Mettaton EX)

"It's strange, but I swore I saw them in the shadows... Changing shape...?" (This is referring to MTT changing his form from EX to his standard "box" form)

Mettaton was able to transform into EX prior to your battle with him. Your encounter with him was just the first time it was revealed to you and all of the Underground.
