[SPOILERS] Series 8 Theories?

[JHyde]

Spoiler: show

In the article released a few weeks back, the implication was that Ruth's debrief and intellectual bonding with Lucas was more long term, so hopefully we can assume Ruth is back for at least half the series.

I like the idea of a possible Juliet return, but only for one episode. There's already a lot going on this series, Yalta's an old storyline, and it would make more sense to fit her in with the Nightingale gang.
