Reasons to not be convinced Root is dead
This isnât an attempt claim that Root is alive or that any of what happened was planned, but to clarify that based on what happened and what would be consistent with this show (which has always been masterfully consistent) there is no way to claim that she is in fact dead.
First and foremost: obviously, we didnât see her die. Nolan said âsometimes the hero dies alone in the darkâ, but any TV writer knows you have to show it if you expect anyone to believe it. Yes, it allowed for that big reveal with Harold and TMâs voice, but that shouldnât have taken priority over giving Root her final moment and the audience any sort of convincing closure for one of its main characters. This show has always shown the final moments of any large characterâs death and left no ambiguity unless there should have been. We always got that final shotâthat brief moment where you get to look at their face as they acknowledge that they are about to die. (They also had the perfect opportunity to show her dying in âReturn 0Ⲡwhen TM was visiting people in their final moments.)    Â
The cochlear implant. Considering Samaritan has known about the implant for a while and had access to her body at any time from the moment they shot her, why would they wait so long to get to it? Getting that implant would have been one of their top priorities since âAsylumâ. Â Â Â Â Â
So counter argumentâRoot and TM have given up the teamâs location before in order to get access to something knowing full well theyâd be able to handle themselves (âMost Likely ToâŚâ).
This excuses why her body wasnât cremated, which would have been the most logical choice, and allows her body to missing.
Thereâs no way TM wouldnât have thought of how important it would be to destroy the implant. It was the single most important piece to her communication with the team and contained the exact information needed to reveal all of them. It would just be plain stupid for an Artificial Super Intelligence to forget that (She literally says âmy badâ). Â Â Â Â Â Â Â Â
Theyâve faked a dead body before. Shaw was poisoned and passed for dead well enough to convince a bunch of paramedics in âRelevanceâ. Considering Fusco was the only witness to Rootâs actual body itâs not a stretch that he could have been fooled. Heâs the least skeptical of the bunch and has no medical training to be able to read the body. If any other member of the team were there they would have confirmed for themselves.Â
How did the machine not detect Jeff Blackwell? Heâs crossed paths with the team enough for the machine to have a close eye on him above most others, so TM should have seen something like that coming even if he was using the shadow map. (I made another post about Blackwell after 5x10 about how odd of a choice it was to choose him as the shooter when heâs failed all of his previous (and future) missions) ¡         Â
Root just happened to upload that software to the machine the same day and said all the things she would need to say to Shaw and Harold for them to process her death the way they needed to in order to move forward and take down Samaritan. This show has a lot of happy coincidences and foreshadowing, but thatâs a bit much even for them.
The whole giving her a voice part also happened in the beginning. We learned in âIf-Then-Elseâ that the machine is capable of predicting exactly what characters would say in any given scenario (âWhat goodâs saving the world if we canât enjoy it?â) so it could have predicted that Harold would respond to a conversation about giving the machine a voice by letting it choose one.
ROOT HAS NEVER WANTED TO BE THE MACHINE. The âRoot becoming a Godâ concept from the writers isnât consistent with her character. Yes, Root was all for transcending and becoming more than just human and having an ever closer relationship with TM, but she never would have wanted TM to become her. Root has always just wanted to be her greatest servant (âShe sees everything, but thereâs very little she can do about it herself. Thatâs where I come in. She tells me what to do and I do it.â). It was Rootâs physical body and actions that made her so critical and important to TM.Â
Root didnât need to be dead for TM to take her voice. But from the writerâs perspective it was moving to have Amy Acker play TM (which would have been strange if Root was still around), it helped communicate that TM really does care because of how sentimental she is towards Root, and they needed Harold to finally have those full-on conversations with TM without him sitting at a computer screen. It was simply the quickest way to âhumanizeâ the machine so the show could end the way they wanted.Â
Root would absolutely fake her own death. Thatâs probably the biggest reason why none of us are convincedâbecause she totally would. Again, not to say this was planned, but the writerâs would have to give us a lot more proof if they wanted us to believe she really died. Sheâs the master of manipulation and disappearing acts and has survived far worse. Â Â Â Â
The only âsolidâ evidence that she died is that the writerâs say so. If writerâs have to convince us of something outside of the show itself, they clearly did something wrong, because they didnât write it in their story.
Ultimately it seems like the writers were playing at a weird line of making her dead for the sake of ending this season and wrapping up Harold and TMâs original plot while still leaving enough holes to make it possible for her to return if this story were to continue. So, because all of those open windows exist and that it would be consistent with this show and her character for her story to not be over, itâs simply SchrĂśdingerâs cat all over againâŚ
