I don't think it's an affair with JJ and Cruz. Likely it has to do with something left over from the State Department, something she can't talk about as it's an active case. She mentioned the cameras in regard to foreign intelligence, so maybe that's involved as well. Maybe she and Cruz are sort-of spying on the FBI? Like maybe there's a mole or a leak, or they're making sure there isn't one. Meeting for runs is risky, as maybe it would put the investigation on notice to the bad guys. IDK, spies and cloak-and-dagger stuff are not my forte, but hopefully you know what I mean.

I like Cruz well enough. He didn't interfere, he helped, and he's different from Strauss in personality so they're not just C&Ping her. I'm curious to see how that'll play out.

Also, Reid and Blake geek-out. <3

Randomly, for those that watch NCIS: LA, I totally want Eric, Nell, and Garcia to hang out together.
