Sharon is braces-free (or brace-free, as she calls it) for 24 hours by her dentist. To facilitate her goal of kissing Alden under peak conditions, she volunteers to babysit her little brother, Josh, so that she can have a make-out party at her house (Connor is specifically excluded). All plans to secure the Alden kiss go haywire when Josh goes missing and Sharon must live up to the responsibility she assured her mother she was capable of doing.
