The writers of heroes must have serious daddy issues. Peter and Nathan’s father was a corrupt politician, Claire’s adopted father may be one of the villains on the show (HRG), and Hiro’s pops (George Takei) seems to have some issues with his son. But the real question this season is “Who is Claire’s Father”?
The top running theories are Matt Parkman, Nathan Petrelli and Mr. Linderman. Some people still insist it is HRG himself, despite all evidence to the contrary. HRG is NOT her real father. Lets talk a little about the top three.
The argument that the father is Matt Parkman is the father was largely fueled by the following picture:

Matt Parkman:
In the scene where Claire’s mother called Claire’s father he was wearing a purple shirt and had a watch and ring on. The watch and ring is what most people point out when they think Matt is the father. I don’t think he’s her father. Can you see Matt wearing a freshly pressed purple shirt sitting behind a very nice desk in a very nice office? I guess he’s hiding that in his secret lair behind all the broken plumbing in his low rent apartment on his police salary.
Nathan Petrelli:
Nathan is a clear favorite among fans and I consider him a very likely candidate to be Claire’s father. It would further the story, create more tension at him for Nathan and possibly give him a stronger tie to what happens. It would also more closely link Claire to the main characters on a more personal level. In the last episode she was joking with Zach about finding an Uncle and her interaction with Peter could very well have been that kind of relationship making that remark a hint about the father. Some people have speculated that Claire and Peter would be love interests on the show, but Peter is 26 and Claire is 15. Though she is in Texas, I still don’t see that happening. Nathan is very likely candidate as the father.
Mr. Linderman:
It’s about time Linderman was introduced as more than just a guy behind the scenes and according to TV Guide Linderman will be introduced soon and by the end of Feb. sweeps they will reveal Claire’s father. Tim Kring (Heroes creator) has said that it would be important to cast the right person as Linderman and as of yet I haven’t seen anyone on IMDB or any other rumor sites as who it would be. Some people have speculated that Eric Robers would be playing Linderman but he’s listed as playing someone who works for HRG. Every character has a connection to Linderman so far except for Claire and this would give her the best connection possible. It could explain his obsession with all things Heroes and why he seems to be collecting all information he can, maybe he’s looking for his daughter. Mom has abilities and I’m betting dad will to. I think Linderman is my favorite as Claire’s father.
We’ll find out very soon, and I can’t wait. Who do you think Claire’s father is?
[b]Update:[/b] As of the most recent episode, “Distractions”, Claire’s father has been revealed to be non other than Nathan Petrelli which means pretty much everyone is connected in some way or another.
