i had about an hour left on my flight last weekend, so i scrolled through their free entertainment options and settled on a rewatch of episode 3.
so so so fucking good. a couple things i noticed this time around that i liked - mostly centered around what they decided not to show in the flashbacks that illustrate the evolution of the relationship between bill (offerman) and joel.
bill tells frank "we're not going to have friends", which of course cuts to them having friends over for lunch. at the end of that flashback, bill and joel are talking and joel says there will be raiders. he also says "we have things you don't have here" and he includes medicine in that. but bill's posture at that point is still "thanks but we're self-sufficient".
the next scene is raiders hitting, just like joel said, at night, in numbers, well-armed. they shoot bill (as has been covered upthread, like an idiot, in the street). when frank brings him in and lays him on the table, he repeatedly yells, "call joel, he'll take care of you". it's clear at this point that the bill-joel relationship has evolved and certainly includes a lot of trust now, even though we don't see it. when he thinks the end is near, he specifically says, "call joel".
fast forward to the next flashback on the porch, and the twist is that it's frank in the wheelchair, even though we just saw bill get shot. eventually they're inside and bill is giving frank his pills (great little offerman moment, as he has little nicknames for the pills, big browney, and such). obviously they wouldn't have known he would get sick, so it's pretty clear that they've worked with joel to get him the meds he needed. again, shown but not explained. love the lack of exposition.
then of course the note - "to whoever finds this, probably joel". it allows space for the viewer to imagine the relationship that bill had with joel over the years, even though they only share one actual scene together. it's been 20 years, so it trusts us to put the pieces together ourselves. that's rare these days with the low attention span of a normal audience. i appreciated that.
(some of these scenes might not have been right after one another, but you get the idea).
