Quorra the African Grey Talking - Hissing, Up up, I'll be right back, Quorra, Hi

Quorra, our 14 month old African Grey talking a bit. She starts off by hissing. When she starts talking, she's saying "up, up. I'll be right back. Quorra" You'll hear her make some other noises. Later on you'll hear her say hi. After the first bit of silence, she says "what?" She says something towards the end of the video, but I can't even make it out. lol
