I'd suggest watching the first half of season 5, then watching the latest episodes. It's been over a year since the season 'break,' so many people heave forgotten what happened in the first 8 epidodes - I know I had.
Th whole season arc makes much more sense if you do this, otherwise it seems disjointed and fragmentary. In other words, WTF is going on and why are they behaving this way?
I took the opportunity to watch the entire 4.5 seasons up to 5.8 only AFTER watching episode 5.9. 5.9 made no sense without the context of 5.1 - 5.8.
Now I get it...
