McGee looks like he's checking out Ellie's hair but what we really want to hear are all of the Grease references DiNozzo is destined to make when he sees this costume.
And who is this? She's obviously in law enforcement. If we had to guess we'd say she may be someone from DiNozzo's past but we'll have to wait for NCIS Season 12 Episode 6 to find out.
We wouldn't want to have to face Gibbs when he finds the people behind a fraudulent charity taking advantage of people searching for missing military personnel.
