Following last week's two-part premiere, Helix returns tomorrow night at 10 PM ET on Syfy with the new episode "274". The network has released a new clip, featuring Dr. Alan Faragut (Billy Campbell) trying to reach Dr. Julia Walker (Kyra Zagorsky), who is paralyzed with fear while watching an infected woman attack one of the security team members. We also see flashbacks to Julia's strange encounter with Peter (Neil Napier) in last week's premiere. Take a look at this intense new footage before tuning in to this new episode tomorrow night on Syfy.

With the number of infected rising, Alan forces Hatake to open up a new section of the base while Julia tries to make sense of her encounter with Peter.
