Who's Hana? an dher father????

Hana is a character primarily in the online graphic novels, although she made an appearance in the episode Unexpected in the first season. She used to work for the Israeli military, but was forcibly inducted into the Company. She became aware of her ability, the power to receive and transmit electric messages. She did some work for the Company and then went against them. She contacted Ted with information about the Company tracking device.

It's been a while since I read any of the graphic novels, so I'm not too knowledgeable on the specifics.
