After rewatching "Powerless" for research purposes a thought entered my mind: What if the Haitian was responsible for shooting Nathan at the conference?
I don't know if this has been discussed before by fans, but I'll give it a go anyway. First of all, we know that the Haitian has an ever-changing alliegences with people ever since last season, and he does have the ability to block other people's powers from around him. Perhaps that is why neither Matt nor Peter could sense someone was planning on shooting him in the middle of the press conference. Also, the Haitian kind of disappeared after helping Bennet locate the rest of the paintings, and it is these disappearances that are kind of interesting. It's the same like S1 when he was there and then he wasn't, particularly during the most vital moments of what's happening. Maybe the Haitian is back to being underneath the Company's wing.
Or perhaps it was Noah Bennet's doing after reluctantly being recruited back into their facility, that's another thought. Especially since Bob came to him for that deal to stop Claire from exposing their secrets, perhaps knowing what Nathan was planning on doing this was his first assignment to reassure them that he was willing to do their bidding once more. Which is kind of poetic irony, Claire's father shooting her father, and losing both in the process.
The only thing I'm wondering about is Angela Petrelli's words in the end. Perhaps she was chatting with Bob since if she were talking with the Haitian she would've spoken French, and she hardly knows or has never had particular friendly contact with HRG. So, I don't know. Again, speculated theories until Volume Three.
Obviously the Company recruited Mohinder not only for his blood and knowledge and moral compass keeping them in line, but also because he possibly has family ties to that organization. It's not news that his blood carries the antibodies to cure the original sample of the virus, but having him work in the same place that possibly experimented on his sister is, whether he knows it or not.
Shanti Suresh was the first to carry the virus, as they've titled it the Shanti Virus due to her being the first victim and carrier of the deadly disease. You've got the wonder how the virus even came to exist or even how Shanti even acquired it. Like, was she already a carrier and the Company decided to experiment on her and accidentally causing a mutation which creates this virus that is lethal? Or was Shanti's power something like Maya's and it was messed with too much from experimentation and thus doomed to ever be cured (making it like Mohinder and Shanti could've been what Maya and Alejandro were, the yin-and-yang of abilities via blood)? I've been going back and forth between the information we've been given about the virus in general -- Bennet said that the Company created the virus, and perhaps they did but only after finding a way to cure Shanti from whatever sickness she had. But then in 1977 Victoria Pratt had said they discovered the virus in Shanti's blood. Perhaps Shanti did have a softcore version of the virus, but again with too many experiments it could've altered it and created another level of mutation after the attempts of curing it.
Though it makes you wonder, how did the Chandra Suresh come into contact with the Company? Or was he even aware that the Company existed and instead was tricked into believing a colleague or someone he knew could help his daughter with her special abilities or find a cure for her because of her "sickness".
Whatever it is, every single individual that's been infected with the virus has been connected with the Company in some form or other. Now Mohinder being there, some think he's being duped but I honestly don't think he is. He believes he can do some good from within their facility and I think he's right, especially since Bob has been bending over backwards to meet his demands. However after "Powerless" in finding out the Company has been purposefully using the virus to experiment on Sylar, thus keeping him alive when assumed dead to the rest of the world, he'll have to really confront Bob about this issue. At least, I'm hoping so. Mohinder has come such a long way from the beginning of the series, and I would like to see him take charge of what the Company is doing in hopes for altering the way their operation works.
But more about the Company later though, because there's much I want to discuss about them.
