No one seems to be discussing the question that could it be Sylar be the one infected with the killer virus instead of Nikki/Jessica. Was not Sylar placed in a seclusive area with a Company person? Wasn't Sylar devoid of his powers? Why should we assume that his loss of powers was due to his injury and NOT a vaccination of the virus by the Company? After killing Candace and attempting to gain her powers, he went into severe pain. Was this from his injuries or from a change in the virus in his body? It is an interesting consideration especially since all the attention is spent on Nikki and this would be a surprise ending for the shortened season and probably would mean all the Heroes must get together to stop him.
My second point is the question of the Invisible man. Since it is becoming more and more apparent that HRG is going to die; is it possible to tie in a return of the Invisible man? It would be an interesting story to have Claude watching HRG all through these past few episodes, and when HRG dies, Claude comes to Claire to instruct and warn of the things HRG was trying to keep from her.
