I also forgot to mention that Peter should have just phased through the vault, even though it's more dramatic to stand there trying to rip it off it's hinges with telekinesis. Peter 'vadering Hiro was pretty unnecessary too.
It seems that Mat's mind control does not work on someone with mind control and a strong will, so surely Maury could have escaped his commands.
No remember, Pete doesn't know that he has DL's power of phasing through walls... He has the invisible guy's power which allows him to go invisible but he can't phase through objects...
Also I agree with DS that Pete will probably wanna find Adam in order to revive Nathan... And good analysis of Noah being the one to shoot Nathan. Sylar's back baby... hopefully there's some big epic battle between Sylar and Pete next season..
And Nikki can't revive unless she somehow escaped because she was incinerated in the blast, no way you can revive from that..
Overall, very nice episode and a good way to finish it off.
