Doppelgänger had the hard task of accomplishing a lot in 45 minutes. While mostly successful, this season feels like it's facing an uphill battle now to become truly memorable.
I think this might be my favorite episode of the season because it draws on some of the show's strongest and oldest relationships (and also sidelines most of the new recruits).
Things are starting to turn around with this pivot towards Diaz as the main villain. But it feels like everything taking place in this episode should have happened months sooner.
