On Helix Season 2 Episode 3, Sarah and Peter discover what's in the woods when they leave the abbey to retrieve some specimens. Meanwhile, Julia encounters Hatake in the future, but he's not quite sane.
Major Sergio Balleseros: There are people in the Army, myself included, who are wondering if this outbreak was an accident. Dr. Doreen Boyle: You think Hatake did this on purpose? Why would he do that?
Dr. Alan Farragut: This secure lab allows us to separate vectors from those who are just infected. Daniel Aerov: Vectors? Dr. Alan Farragut: It's what we're calling the infected who are physically attacking others to spread the disease, like Peter.
