Later they realize that the “virus” was a ruse to set them against each other
it’s their employer who wants them “offline”, to initiate “PROJECT REBOOT” [also film title]
It was their parents (they are brothers!) who shaped the network
Then planted it in them to protect it from the employer (much like the ninetails sealed in naruto, but rendering them cyborgs)
Not that it matters, but in Act III..
One or them decides to die (fake his death)
And together they defeat their employer!
The film resolves with their brotherhood restored,
they undergo an operation to physicalize (is that a word?) the server & rule it together.
