Few pieces of Bojack's inner dialogue and struggle reminded me of very familiar situations. The ending sequence kinda floored me because...the same as before!
Hollyhock: Like, sometimes I have this tiny voice in the back of my head that goes, like, " Hey, everyone hates you! And they're not wrong to feel that way! "
Bojack: I know what you mean.
Hollyhock: That voice, the one that tells you you're worthless and stupid and ugly...
Bojack: Yeah?
Hollyhock: It goes away, right? It's just like a dumb teenage-girl thing, but then it goes away?
Bojack: Yeah.
Well of course it does not necessarily go away, most probably it won't but also, as an afterthought and possibly am reading too much into this, Bojack by intentionally lying maybe it bodes to what have preceded between them when he told her he will never lie to her again. He does now but he does it cause he loves her and she doesn't have to know yet.
PS: Levels of quality again high in series 4 and what a wonderful episode the one with Beatrice as a kid.
