Watched 17, now waiting for 18 to download.
And I just found a website that has the episode summaries up to 20. Ngh, it's tempting...
Oh and my mum took the piss out of me because she said "wait, what episode did you say you got up to?"
"Uh, 17?"
"And you watched the first one on Monday?"
"Maybe...?"
So yesterday I told her just to try watching the first one. After it finished, I got changed ready to go out and I come back in the room to hear her tell my sister "put the second one on..."
I came home last night and they'd reached episode 7.
Heh.
