The stuff with Mr. Petrelli building an army, and using Maury to do his dirty work (yay with answers about Linderman!) was also ominous to see...excellent stuff. The fact that Mr. Petrelli is stuck in a hospital bed, but still able to pull the strings, is a bit cliche, but really does make him seem that much more imposing.
Do we know/Does anyone remember Pa Patrelli's power(s)?
It certainly seems like it might be something to fear, unless it's his position in his company that gives him power over the mindbender.
