Last 2 Eps on Netflix
I thought I would mention this as I didn't see a subject line for it. The info was buried in one discussion, and there was a news item attached to this IMDb page that some may have missed.
Basically, if you have Netflix with streaming, you can watch the last two unaired eps (and the rest of season 2) there.
The news article also mentions that ABC is making them available, via Amazon and other sites, on a pay per episode basis.
If you're a fan of the show, they are greatly worth checking out. I really like the last episode featuring a lie detector. There was some great rapid comic dialogue in that one with truths, lies, and the differences if someone knew the other person knew they were lying or not (you'll understand, hopefully, when you see the ep).
Cheers!
