Season 4 - Rumored New Character - Who is Roy Stark?

There has been a rumor flying around the Internet about a new character that will debut in Season 4 of The Walking Dead. 

Tvline.com is reporting that The Walking Dead team has sent out a casting call for a new series regular role of a character called Roy Stark, who is a former army medic who had serious issues even before the zombie apocalypse.  Apparently, he's a loner in his early 30s to mid 40s is still charming, self-deprecating and confident around people.

If I remember correctly, the same thing was done last season where they had a character named Manuel, whose name was eventually changed to Tomas by the time season three came around.  Just because they're casting this name right now doesn't necessarily mean its going to stay that way.  It could be a false name for some other character like Abraham from the comic book series, which would make a lot of sense for him to be introduced into the television series. 

I don't believe Abraham was a former army medic, but I think he was an infantry-soldier-type of guy.  It does interest me that they are a calling for a series regular this early, which probably makes me think that he is going to run into the Governor at some point. 

I think Rick has enough people on his side and the Governor has to start recruiting some people to his side if he wants to stay relevant.  I would hate to see David Morrissey come back and play the antagonist of the series if he has no men.  If the Governor only has three people, what are they going to do?  He's not going to be able to launch a full out assault on the prison like he did before.  He could commit scare tactics like sniping people from a distance when they least expect it or try to assassinate some people. 

Again, I'm leaning toward the possibility of this new character, with a group of his own, running into the Governor and the former Woodbury leader will try to convince him to help him attack the prison with possibly some other soldiers or other military-type guys to increase the man-power of the Governor's group.  I'm also interested in whether the Governor knows anyone else outside of Woodbury or if he knows any other locations in the world where he can set up a base.  

The Governor can't behave the way he did before when he had Woodbury because he is not going to want to take someone in, find out where they are and go steal their stuff.  He is going to want to be really nice to them and join up with them so he can get more people on his side.  That's what I think they are going to do with this new character, but they could change the name like they did before season three.  I always love getting military-type people involved in The Walking Dead.

Just as a little side note, I still want to see a tank in the television series.  Maybe Roy Stark and his group will have a tank, which would be awesome.  Could you imagine a tank assaulting the prison?  That would be really tough to deal with, even if the Governor is out-numbered.  If they had a tank, that would be really hard to mess with.
