Puck tells Quinn not to leave and Shelby grabs her wrist and pulls her back slightly. Shelby wants Quinn to be involved with Beth's life, but only if Quinn cleans up her bad girl act. Quinn is not impressed by the way Shelby has requested her clean up and argues that Shelby isn't Beth's mother and storms out.

Quinn attempts to prove Shelby as an unfit mother by placing objects around her apartment, such as hot-sauced labeled "Beth's," Baby Botox, and books titled, "Selling Your Baby Back to Russia" and "Basics of Baby Sacrifice." She planned on calling Child Protective Services later, but Puck removes all the items before she gets the chance.
