I was wondering does anyone think we will eventually hear about Mr. Flynn (i.e. Phineas and Canadace's actual dad) and Mrs. Fletcher (i.e. Ferb's actual mother). Are they going to show up at some later point. Are we in for a "very special" (read "very sad")episode down the road? I know that there are some people who have speculated that Dr. Doofenshmirtz is Phineas's real father, but for several reasons, this is not likey. So your opinion.
