Honestly there’s just so much in this episode, that even after several viewings I’m sure you’d still be picking out small references and easter eggs here and there.
I watched the reviews and spoilers before watching the episode so that I could appreciate them all in my first go for this exact reason; they always shove so much into these kinds of episodes that it's near impossible to get them all and I'm here for it lol
hopefully, it'll be possible to opt out somehow.
