Season 2?

In an earlier post one of the group put a link to an interview about why there is the possibility of a second season. I haven't read the interview (yet), but I feel that a lot of the focus of the show was tied up at the very end (including "My name is..." I Don't want to spoil it, but a common male name). There are points that can be delved into dealer, but are they warranted? I can see in being a cat and mouse game, but prefer the ending as is. Any feel the show needs a second season, or are they happy (content, ok) with the ending we saw?
