Favorite Episode?

What was your favorite episode of Series 2, and why?

It's really hard to pick a favorite from Series 2, I loved a lot of them so much. If I had to choose, it would be either:

I Spy Apocalypse
I loved this one because it was chilling stuff, the team not knowing if it's real or not, Harry faking illness. It was all brilliant, pushed everyone to their limits, but they were still a team at the end.

Blood & Money
I loved this one, because business espionage is one of my favorite kinds. Seeing Danny on the trading floor was fantastic, and the storyline itself was very clever.

Spiders
I liked this one simply because it has hackers in it, and being a computer guy it was a very good episode.

I know I picked 3, lol but they are all on the same level for me.

So what's your favorite episode from Series 2?
