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
awesome work; it gave me goosebumps. lol
