Firefly(The Series) Questions?

Okay, so ive recently really started to like and watch the series
Firefly(Very late i know, but i was probably like 6 when it was
airing), anyway, do you ever think there will be a second season? It
kind of left alot of unanswered questions, such as River and the Doc,
and what ever happed the Saffron(or any other name mentioned), not
that shes a major character it just kind of left of wierdly witih her
character, Also returning back to the Doc, the relationship between
him and Kaylee, and also the relationship between Mal and Inara, and
them being chased down by the Alliance constantly..Thanks for your
answer.
