Two major things stood out to me in the last episode. Mikhail, Philip's first son, is anti-State. And Philip, after his EST meeting is now more than ever considering being done for good. It's been something that's been going on since the first season. Philip just isn't into it heart and soul like Elisabeth is. With Mikhail now on his search to find Philip, these things will be huge.
On that note I've definitely noticed how things have gradually started to tilt in terms of good and 'evil' with season 4 definitely starting to cast the Soviets in a more villainous way with the biological weapons. Standing out to me was William being vocal about not wanting to go through with the mission, and Oleg leaking the info to Stan, all because of what seemed like a moral responsibility.
Elisabeth is also starting to be cast as an antagonist of sorts. Ignore the fact that Paige as a character is frustrating as f*ck, but that scene where Elisabeth totally lost her cool on Paige, more or less laying it on her that she has to check in with Pastor Tim and Alice every day because it's all completely her fault that this has happened and that it's all on her if the family is destroyed. Like yeah you're kinda right (and kinda wrong) but that's not what a scared 15 year old girl needs to hear right now from her mom. Also the whole merciless killing of the mugger right in front of her and then being pretty unapologetic about it was pretty whoa.
It's also frustrating me how Elisabeth was just so gung-ho about bringing Paige into their world in Season 3, yet she is still being dishonest and hiding stuff from her. I get that there are things that Paige is totally not ready for, but the way Elisabeth just totally dodges everything with dumb mommy answers just has me like OH COME ON at this point. Really happy Paige called her out on it.
Also I am noticing that Henry is starting to feel left out and definitely paying attention to how much his parents are in with Paige and not him. Just little comments about how they'd never let him stay home from school like Paige, and not watching the super bowl with him, and above all (and I'm sure this will also be huge down the road) his spending lots of time with Stan and looking to him more as a father-figure than Philip.
There's still quite a bit of this show left with two more seasons and 26 episodes, assuming the last two seasons will be full length at 13 episodes each, but if I had to call it now on how things will fall apart (because let's be real we all know they will), I think it will be in the form of Henry finding out and not being ready. I don't think he's going to flat out tell Stan, but I think he'll let something really subtle slip, and Stan will be able to put it together really quickly. I mean now he already knows the people he's looking for are a married couple with two kids.
All in all I loved season 4 and if I had to rank the seasons I would say 4,3,2,1. I really think this shows just gets better every season. More suspenseful, more personal, and the writing and directing has become so articulate. I'm really starting to feel for these side characters that Philip and Elisabeth just use and throw away. The stuff with Martha and Young Hee this season was just heart-rendering. Hoping the show does well at the Emmys, but I realistically know that with all the tough competition in each category that its chances are slim.
It was a nice callback to other job-doing scenes like when they stuffed a body into a briefcase. I like those scenes because it's a reminder that the Jennings' work isn't all wigs and espionage. Sometimes it's just serious, shitty legwork.
It was also a fun watch because all the tension comes from our knowledge of the characters. I've watched the show enough to be uneasy when they're doing something tedious like digging a big damn hole in the ground. And we know the characters well enough at this point that when their buddy cuts his hand it isn't a question of "if" he will die but "when" and "how."
