3x09 is an amazing ep
And thank god for the return of Mac!
Haven't watched all of 3x10 yet, but I saw a couple of ads for it on both Trouble and Living. And they are pretty spoiler-tastic! For the next couple eps anyway. So if you don't want to be spoiled about what's going to happen, I'd try to avoid them - it's so annoying when the TV channels do that!
