We're not sure what Claire's mom's ability is - except for the fact that she lit her cigarette by producing a flame with her fingers. I'm sure we'll learn much more about her next week.
I, too, am very intrigued to see where they go with Takei as Hiro's father. And, even more, who is he? He's not Linderman, who I'm sure will be very interesting once he's cast, as it seems to me that he'll be the factor to tie other characters into Nikki/Jesse's storyline.
Great episode last night.
