Yeah wish they would of have done that with cryokenesis, though James walker could still be the one with it, and sylar just froze his body afterwards. Not the greatest episode but i did like them showing Arthur and Linderman together. I think Hiro will still freeze time before Artur can steal his powers, or maybe mid way through stealing them as a way to weaken Hiro up a bit.
Doubt it, Molly's dad was frozen mid bite of his breakfast.
I get the feeling Ando might intervene by attacking Arthur distracting him so Hiro can teleport away, I don't think freezing time would work since Arthur has that power and when Hiro froze time to kill Adam Monroe Peter was unaffected, this could potentially involve him having to leave Ando behind and explaining how he turns against Hiro for being abandoned and gets given a power - i.e Arthur captures him and experiments on him.
