Still fond of Grant (recurring guest star SHARIF ATKINS), the man she almost married, Shelly takes him to lunch in an effort to remain friends. But this becomes a monumental task after he informs her that he's newly engaged--and introduces her to his new love. Meanwhile, Nick and J.T. start to hang out with a youngster through a local Big Buddies program, but they soon clash over their very different mentoring styles. Also, Rita moves into her new loft.
