I was a little disappointed that they didn't show parts one and two in one go, because this episode, by itself is a little lacking.
Some more nice origin flashbacks and a couple of intriguing things (like a potential long awaited upgrade for one character, and some more clone appearing but not as you'd expect), but all the pay off looks like it will be next week.
It also doesn't look like the ending I (and I think others) was expecting but it could give a wrap up to the main overarching storyline of the series as a whole.
