Leslie and Ron -
I think I figured out why the last scene in Eagleton made feel so many things:
The give-and-take in this relationship is usually only seen in the background, where one of them pushes the other just a little bit to get things that are central to the plot done. Usually we see them being firm opposites who still respect each other and respect that they are what they are - their interactions aren't about changing each other, but working around it.
Then we get things like this, storylines that focus on the tangible ways they affect each other, and ugh, just. this friendship is fucking flawless. It's shifted a lot over the last couple of years: it went from the way he used to kind-of give her things to do because he was lazy and knew she'd do them all, to him giving her things to do because he trusts in her ability to do them, to him giving her things to do because he trusts in ability to care for them, and now we have him trusting her ability to care for him.
And that's significant, because this man's best friendship was someone he never talked to, and he's had two awful ex-wives, and he generally has fun being alone. It's not that he's insecure in his friendships with other people, not at all - he's not some sad, lonely old man or anything - it's just that he's had little reason to think he has similar security with anyone else. He has reason to believe in her a little bit more.
When he smiles after Leslie tells him his party next year is going to be "a rager", you know he's figured out that that's not happening. I've been thinking about this and even the way he actually teases her in Woman of the Year gives me feelings, because I can't imagine him giving into the urge to do something as simple and friendly as that, you know? Maybe he hasn't had much reason to even think of doing something like that.
This friendship gives me joy. It's my favourite relationship on the show, hands-down.
