Season 3 continues the premise of a time-travelling cop
after time-travelling terrorists, but things get even more more complicated,
and even more morally ambiguous.
Brilliantly, the short time hop at the end of season 2 is not
used as a reset, but rather makes everything more complicated and darker,
and changes lots of relationships.
The flash forwards show how morally compromised Kiera really was as a future cop,
and now she is beginning to realise that.
By the end of the season it is clear that there is no way for Kiera to return home:
the future has been changed, and she no longer wants that specific future, anyway.
So what comes next? Well, it looks as if the Time Guardians are about to up their game…
