Orphan Black 507: Rachel questions her place in Neolution

Orphan Black‘s final season has been a strong one, filled with startling revelations, shocking deaths and deep dives into the inner lives of the Leda clones, but this week’s new episode—which puts Rachel under the microscope—is easily the best of the season so far. It’s an intense character study from the teaser on, and it genuinely keeps you guessing right up to its stunning, but fully earned, conclusion.

Here’s what Bell Media teased about “Gag or Throttle,” written by Renée St. Cyr and directed by David Frazee.

As P.T. Westmorland demands a more aggressive approach with Kira, Rachel discovers a dark secret that makes her question her place within Neolution. Sarah fights to save her daughter.

And here’s what we can hint about the episode.

Kira becomes a lab rat
With Susan out of the way, Westmorland and Coady push for more invasive procedures to be used on Kira—which forces Rachel to face some uncomfortable truths about Neolution.

Just who is P.T. Westmorland?
Last week, it was revealed that P.T. is a fraud, and this week Cosima digs further into his past.

Auld lang syne
Season 5 has seen a lot of old friends and foes return both via flashback and plot twists, and this instalment is no different. Count on seeing at least three familiar faces pop up.

New wig alert
Expect more than one character to sport a new (or old) ‘do.

New music alert
There is a new musical cue near the end of the episode that truly elevates the drama. Writer Renée St. Cyr tells us this very deliberate musical choice came courtesy of director David Frazee. (Look for my chat with Renée after Saturday’s broadcast.)

That’s about all we can say about the ending.

Orphan Black airs Saturdays at 10 p.m. ET/7 p.m. PT on Space.
