Here are the questions I had after the finale:
- Why did Nathan have to fly Peter up into the sky? Peter can fly.
(okay, this one has been reasonably answered in this thread)
- What happened to Nathan that caused him to grow a pair and decide to save his brother?
- Why the HELL didn't they make sure Silar was dead?
- If Parkman was taken away by ambulance, why wasn't Silar's body too?
- If Silar's body was already gone by the time the ambulance arrived, how did they at least not notice the HUGE blood smear leading to the sewer?
- What was that thing crawling down the edge of the sewer cap? It looked like a slug to me.
- Does mother Petrelli have a power? Is it the ability to bend people (or her sons) to her will?
- Who is the super bogeyman who can see Molly when she thinks about him? Have we already seen this character or is it forthcoming?
- Did the Petrelli boys really die?
- Why did Hiro end up so far in the past? He's gotten pretty good with his powers, that seems like pretty poor teleport.
