Which episode of supernatural is the one where dean has a child

This one?

Episode 2 "The Kids Are Alright"

Is it possible? Is Dean a daddy? I can't say I'm surprised to hear that Dean could have a spawn of his own. In this packed episode Sam and Dean need to stop the changeling that is overtaking children and going after their parents. This episode has all the ingredients of a great show: humor, action, fear, and a clever storyline.

Dean decides to pay a visit to a one-night stand that he had eight years ago with a woman named Lisa. It turns out that Lisa has an 8-year-old named Ben who is a spitting image of Dean. The kid is an AC/DC fan and refers to girls as "chicks." Doesn't that just scream Dean? The best scenes in this entire episode were between Jensen and the little boy. I could not stop laughing at those two.

You see another side of Dean - a side where he wants to have a normal life and maybe settle down and have a child. He wants something other than his car to leave behind as a legacy. I have to admit his reaction to seeing Ben was hysterical. At the end Lisa admits that Ben is not Dean's son, though I wonder if he really is by the look on her face. Dean seemed a little disappointed, but it was nice seeing his sweeter side.

The biggest twist in the episode came at the end when Sam learned that Ruby is actually a demon who wants to help him. She wants to find out what exactly the demon did to Sam the night his mother died. In return she said she could help Dean get out of his deal. But what about Sam? Wouldn't that get him killed if they break the deal? I can't help but wonder what exactly her motive is and why a demon wants to help a demon hunter. I'm intrigued, that's for sure.
