Continuing with the pre-season 4 re-watch.
I really loved the scenes with Avasarala and Holden's mother (Mother Elise). Shohreh Aghdashloo was great as always, and Frances Fisher also was wonderful. These scenes - coupled with his explanation to the Martian interrogator about not wanting to be the boot on the neck of the Belt - really do give us insight into Holden and what drives some of his decisions.
When Amos turned to Holden and said "Well, that worked out" and just went off like he didn't just have a gun pointed at his head, I was like "Never change, Amos." I'd love to get the backstory on how he and Naomi connected/became BFFs.
Miller's character is still hard to get into at this point. His motivation for the obsession with Julie has never been clear to me (and it didn't get clearer when I read the books either). The more I think about it, the more I think of Miller as the one of audience's windows into this world. Through him, we learn about life in places like Ceres and how Earth, Mars and the Belt relate to each other.
I don't remember him registering that much with me on my first watch, but Elias Toufexis is actually really great as Kenzo. He nails the slipperiness of this shady spy character.
Naomi continues to be awesome, and her and Alex saving the day at the last minute was great!
