Everything links back to the company. Every major villain, hero or event. And in a universe shrinking move even more of the major players are related to each other, Flint being Claires uncle along with Peter and Sylar...
I'm guessing Arthur now has access to Sylays power - via Peter. Wondering if this includes 'the hunger' that Plagues Sylar / gabe. We haven't seen Artie angry or upset so we don't know if Maya's ability will affect him like it did her.
It seems like he's just become far too powerful, Hopefully they'll be handling things in an interesting way, there's only a few episodes left in this volume.
