Right. A glitch is... a part of the game that doesn't work right. When the code's messed up. It makes the character... fizz in and out. Glitches are problems for games, because... because it can make people think the game is broken if they see one. So a glitch can get a game unplugged. [His face droops, as if reliving something horrible.] And... and it's the worst for a glitch, because... they can't leave the game. No matter how hard you try, you can't get a glitch outsider of her game. She'd... go with the rest of the game.
