Minerva and Fred
Fred watched as Minerva sang the song and showed off her dexterity. Even without the knife, Fred was impressed that the girl was as good as she was. Sort of peaked her interest to see what those fingers could do elsewhere. Sure Fred was still new to the whole bedroom thing; however, that only caused her to be even more curious.
Fred grinned when the girl winked at her. She wasn't exactly easy to embarrass, but she did find it nice when a hot girl was flirting. "Well then," she leaned on the bar and looked Min right in the eyes, "In that case. Keep your eyes on me and don't blink."
Assuming Minerva didn't blink or turn away the illusion would take hold. Fred's eyes flashed yellow for a second and the illusion would take hold. She would then pull a lightsaber from behind her back and ignite it. She would then begin to do a number of impressive moves before showing that it was all an illusion and the two were still staring into each other's eyes.
