Candy and Ray

I stopped watching the show halfway through season 3 but as far as I know Candy's "baby daddy" was never revealed however it wasn't Ray's. I think she just slept with someone over there (as we all know her fondness for men in uniform). They did date, briefly, but all of it occurred off screen and apparently it ended pretty badly.

They split in season 3. The baby was from another member of the Army. She got pregnant during her deployment in Afghanistan...reason to send her back to the US.
