Gideon was there, of course, and she basically acted like me when I'm in an unfamiliar church service uncertain when to applaud, stand up, etc. BUT she just did what everyone else did and when Vanya played she cheered her lungs out. She wasn't familiar with any of the tunes that were played but that didn't matter; it was her first concert experience and she loved it!
At the end of the show she presented Vanya with a big bouquet of fresh red and black roses, because never say she doesn't shoot her shot.
