This episode is awesome for the relationships between the team members. It's one of my faves (with the one before being one of my least faves, on account of Garcia getting shot).
It made me feel bad for JJ. "You do whatever it takes to protect your family." That was a great line. :-)
Also I love that the other tech geek is so utterly smitten with Garcia.
Here's my big peeve, though: Garcia is one of a handful of elite hackers in the world, with skillz that make the other geek weak in the knees. So, why is her password to a super-top-secret encrypted file just a string of letters? I'm no hacker and even I know that's pretty weak.
