at the end of this episode, we're taken back to the same room at the end of the pilot episode where tyrell greets elliot with his "bonsoir elliot"
elliot's inner child? is spinning around in a chair, that isn't his according to his imaginary mom and informs the child they are waiting for "him"
who is "him"? elliot? nope. mr robot? nope - "the other one"
father, son & holy spirit? ("you're only seeing what's in front of you, you're not seeing what's above you")
only clues we're left with - the skyline contains the freedom tower, and in an earlier scene darlene joked about elliot's adoption papers being in his mom's safe deposit box
this show has barely any characters it could be left at the rate they're dying off
Also perfectly on theme with the Chinese controling everything & everyone.
Kind of easy to say "we need to gather everyone from our secret group to apoint your successor", but I'll allow it.
Would love to guess who 3rd personality is, but don't even know properly who's officially dead & not.
Btw whoever it is, it could be someone who we've seen dying if the murder was not on-screen & only Elliott saw the body? Not sure anyone fits that bill, just thinking it would be a cool plot twist.
after some rewatching and redditting here's what i've come up with:
in season 1 episode eps1.3da3m0ns.mp4 during the well known dream sequence, angela tells elliot he's only a month old - this would coincide with him introducing us into his world at the beginning of the season.
we also have the sam sepiol alias, which is a recurring alias throughout the show, it's elliot's hacker handle and is also the alias he used during the steel mountain epsiode back in season 1. sam sepiol is a confident prick.
now we jump ahead to last season's episode eps3.7dont-delete-me.ko - at the beginning of the episode we flashback to young elliot and his dad at the movies setting up their trademark m&m's in the popcorn.
elliot is being extremely cold toward's his dad, saying he didn't even want to come, while his dad is hacking away due to his cancer. his dad finally collapses (dies?) and all elliot does is casually pick up his dad's mr robot jacket, go into a theatre, and tell the empty seat next to him "shhh, the movie's about to start."
conclusion?
when elliot was with his dad at the movies, sam sepiol was in control while being so cruel to his dad. so...
either elliot hasn't been the primary personality the entire time and is only a month old during the dream sequence in season 1, and the dickhead sam sepiol is the primary personality, or...
dickhead sam sepiol is the third personality who is only a month old during the season 1 dream sequence
and/or - sam sepiol really is the mogul he presented to the steel mountain employee, and possibly part of the deus group
