Here's what we know for sure, so far. Hiroshi is Julia's father and they both have those bright alien eyes. Julia didn't spend her childhood out west - she was in fact in the lower realms of the Arctic facility. The zombies - or vectors, in Helix-speak - are afraid of Julia. (But I don't recall them being afraid of Hiroshi, which raises an interesting question.) The facility has more viral specimens than "the CDC" - which means, many indeed. And the virus responsible for the outbreak is en route to the outside - stolen - which could result in a billion deaths.
Whew! That's a powerful situation, and it's good to see it finally becoming more clear. But still looming large and unknown is the relationship between the deadly virus, the cure, and the bright eyes. Presumably, from what we've seen, the trajectory is infection with the zombie-making virus, introduction of the cure, and the emergence of the bright eyes in the cured person. That's what we saw with Julia, and likely the same happened to Hiroshi.
But what do the bright eyes mean? Are they an indication in some next stage of evolution for humanity? And is that stage connected to some alien intelligence life? And what does all this have to do with the indigenous people living in the Arctic?
Meanwhile, Sarah's getting worse, and Hiroshi promises her she'll be ok. Was this just to calm her? Or does the virus cocktail hold some hope of a cure for her tumor, which is what I've been thinking all along.
Good to see this show picking up some steam in the cold.
