The news of a third Winchester brother in "Supernatural" had spread early January this year and it apparently is coming true. TV Guide is reporting that an actor has been cast to be the brother of Sam and Dean who will appear in the April 23 episode.
Jake Abel, who has played small roles in "CSI: Miami" and "Cold Case", will play John's secret child, Adam Milligan. John reportedly owns the child through one of his wild adventures while hunting for the demons. Sam and Dean will discover about him in the episode titled "Jump the Shark".
A scoop from E! Online's Kristin Dos Santos last week revealed that the boys will help an "upstanding" Adam who has made an "unexpected and sharp left turn in life".
