Brilliant episode. Loved HRG's backstory and all the insight into his character and motivation.
Claire was fabulous as always and mini!Hiro was adorable.
I actually enjoyed all the focus being on one set of people. It made a nice change and didn't feel rushed or get boring.
Now we just need to find out how Hiro's dad is related to everything. *g*
Oh and if Simone is brought back from the dead, I'm going to be super-pissed.
