Bitto posted... I know people praise D team writing, but I generally like Q team writing. It just kinda sucks that the team is so unlikable, but I liked the reveal and the overall weirdness surrounding Q team. Some foreshadowing regarding this:
1) There's various dialogue for Q team scene that makes way more sense knowing that the leader is an old, blind/deaf, wheelchair-bound man named Q, such as Eric referring to someone on the team as "old man", Sean asking if a certain someone on the team could speak, various Q members saying "you all" rather than "the both of you", and all the suspicion Eric has towards Sean and his concerns about the Q team's leader.
2) The status screen tracks Q's status, not Sean. This is most clear in the Diana/Sigma ending where Q is alive (exactly when the children are birthed) but Sean is dead.
3) Decontamination scene shows 3 corpses and scenes where Sean + Q die often have two thumps rather than just one.
4) Similarly to how Nonary game suggests 9 participants, this is the Decision game. Deci also means "ten." There's also the X-passes, with X being 10.
5) There are various scenes suggesting shadows of 4 people or someone beyond Mira/Sean/Eric: https://imgur.com/a/44wYR
6) The X-passes for Q clearly do not relate to Sean, like how all the other X-passes refer to their specific character.
7) Zero Time Dilemma = Me? I'm Zero. I'm Delta.
8) When inputting an answer for who killed Mira and during the showdown between Sean/Mira/Eric, putting in "Q" and putting in "me/myself" gives radically different answers.
Some of these (And significantly more of the things in the reddit thread you pulled them from) are blatantly coincidental bullshit that somebody tried to call a "clue" ex post facto
Some of them are legitimately good and interesting clues to the whole thing about Delta being there all along.
The only thing really jarring about the reveal scene itself is Eric calling Sean by name after not having done so at literally any other point prior. Which, yes, it would've ruined the reveal if he did. But it also makes no sense for him to start doing so there in particular which makes it jarring.
