This isn't Greg. Rarity's heard the new music, heard the interviews, and this is not the Greg Universe she knows. Either he's far better at acting than he initially let on, or something is terribly wrong. Experience has taught her to expect the latter.

To that end, she arrives at a public autograph session, putting the holographic projector she's managed to get from Silver to good use to disguise herself. When she approaches Greg's table, he'll see a dark-skinned, blonde woman wearing a sundress, a wide-brimmed sunhat, and a smile. She also does her best to disguise her voice - how does Twilight Sparkle talk when she's excited? "It's so nice to meet you!" she chirps. "I'm your biggest fan!"
