NCIS Episode Preview: Welcome, Lily Tomlin!

NCIS treated us to a terrific Tony-centric episode last night (see our NCIS review earlier). Next week, it looks like the focus will be on McGee - and his grandmother, played by Lily Tomlin.

The line between McGee's personal and professional life becomes blurred when the team uncovers a strange connection between Tim's grandmother and a killing of a naval officier.
