Extraordinary episode. "Chikhai Bardo" felt like an insane collaboration between LOST's "The Constant" and the Charlie Kaufman film Eternal Sunshine of the Spotless Mind. The whole episode felt like not only were we learning about Gemma's history, but it also felt like Gemma herself was revisiting and reexperiencing all of her past, while also dealing with Lumon's mad experimentations on her. And yet somehow Mark, thanks to his reintegration, was also on the same journey at the same time, directly with her even if that wouldn't make any physical sense. In the words of one John Locke, we're going to need to watch that again.
With every answer about Gemma's history and her relationship with Mark, ten more questions arise. Gemma's mind appears to be severed and segmented multiple times over, as Lumon expands their...probing?...developing?...reestablishing?...Gemma's memories, personality, free will? I'm not sure. But it is curious how we saw Dr. Mauer recreate at least one memory of her past but with himself inserted, perverting and twisting the memory in the foulest manner. All of these different rooms Gemma visits, named after cities around the world, perhaps represent different aspects of her mind, and if so, what does Cold Harbor represent (and does its Civil War connection have any bearing with anything)?
Which all comes back to the original ponderings of Gemma's existence. Is she a clone, an android, a revived corpse, a computer program, or somehow even a reincarnation? I wonder about the latter considering the episode title refers directly the the Buddhist belief of intermediate state between death and rebirth. Everything Gemma appears to be experiencing throughout this episode directly suggests Gemma is living out her own personal bardo, even if it's a Lumon-operated one that feels closer to purgatory.
Whatever Lumon is up to, they're the coldest, cruelest, sinister bastards on the face of the fucking planet. I have often compared them to the Dharma Initiative from LOST but honestly Dharma could only dream to reach the levels of manipulation and scientific development that Lumon appears to be at now.
Also, let's take a moment to consider how not only is there whole another group of four people directly observing Gemma and doing their own form of macrodata refinement...but also how all four of them look bizarrely similar to Mark, Irving, Dylan, and Helly.
Again, we're going to need to watch that again.
