“Fushigi” is episode ten of season one of Helix.
In the previous episode, “Level X”, Hatake revealed that he was Julia’s father, something that had seemed to be possible for a while. An expedition to Level X to try and recover the core virus failed, because the virus was missing, and it has now been taken out of the base by Dr. Adrian. Alan and Julia leave the base in an attempt to recover the virus, and try to get a message out. I’d forgotten that the communications array had been destroyed.
Some of the injured people seem to be healing rather rapidly, considering the timescale. Who’s on whose side is also rather complex, and alliances may even be in flux.
Fushigi is apparently Japanese for secret or mystery.
