I don't buy for a second that Claire is dead. Kring can claim it until the cows come home, but in the end, there wouldn't be a big mystery about a major character's fate, that is motivating the actions of one the main characters, if the payoff is going to be "there is no mystery, the answer is exactly what we originally told you, she is dead!"
I do find it a little bit off that neither Peter nor Sylar have even been mentioned in passing. Hell, Sylar would be the poster boy of the anti-evo movement. He is basically their worst nightmare personified. He'd be their Bin Laden. I am glad these characters aren't back...but at least acknowledge their existence.
At any rate, episode 3 is just more of episode 1 and 2, which is just more of the original series. Too much going on, too many characters, very little of it connected, and by the time the writers finally bring it all together, the audience will be too worn out to care and it will feel contrived anyway.
Multiple plots are fine, but when you are working with a serialized story (especially in the context of a finite mini-series), the plot needs to be tightened. Each character needs to have a clear and defined role in the plot. The story cannot be just a bunch of random things happening to each character, with no connection to or repercussions for the other characters, and then it all just happens to get forced together at the very end (with very little rhyme or reason). This type of shoddy writing is what killed the original show. Kring clearly has not learned his lesson. I cannot help but feel that his talents would be much better suited to a more episodic show than a serialized one.
This show needs to be structured more like Game of Thrones. There are so many plots and characters that you go cross eyed just thinking about it. But in the end, they are all connected to a CLEARLY DEFINED central plot. All of their actions further that central plot and have effects on the other characters. Sadly, it just isn't happening.
In closing, random theory time: teleportation kid (isn't it a sad statement of how forgettable these characters are when I can't even remember their names?) is Nathan Petrelli's illegitimate son (much as Claire was his illegitimate daughter) and penny guy made the "promise" to protect him to Angela.
