Spinel could faintly hear the sound pattern coming from Johnny's car.  She liked ambient sounds and silence better, but this was nice too.  She unenthusiastically  nodded her head up and down, thinking to ask some questions about it later.  Then again, the other gems would probably already be asking the same questions, so maybe she'd just listen.  As she listened to the music, a fun idea crossed her mind.  She lowered her crossbow without letting go of it, as it wouldn't do to make it look like it was just floating.  Her crossbow vanished to her mild surprise, but she knew she could summon it again.  She began focusing on her natural glow, dimming it to the point that she was barely visible with the intention of going completely transparent as soon as the vehicle stopped and they came out to check for her so that it would appear she'd fallen off.
