In order to prevent the sprinkler system from triggering, infected-Ricky disables the plant's safety network. However, this is exactly what Jack wants, as Mae has already allowed the phage into the assembly line, causing the phage to reproduce rapidly. The assembly line is rapidly overheating because of the de-activated safety system. If infected-Ricky and infected-Julia don't turn on the safety system the assembly line will burst, filling the lab with the phage. The infected-team, who are now doomed either way, choose to re-activate the safety network and get drenched with the phage. Jack and Mae escape the facility in a helicopter shortly before the facility explodes due to a methane gas leak combined with thermite Mae has placed in the building.
