A clip is released for the April 23 episode of "Supernatural". Adam, a 19-year-old boy who calls Dean and Sam to look for John Winchester, is at a diner with the brothers, recalling his childhood experience with John. Dean is suspicious of him but soon draws the gun underneath the table.
Adam, who is played by Jake Abel, claims that he is the son of John with a nurse. Dean and Sam agree to meet him with the assumption that he is a demon trying to lure them into a trap. When they found out that Adam is really part of their family, Dean is infuriated by the fact that Adam was raised "normally".
The episode is called "Jump the Shark" and reportedly, there will be a tribute to the late Kim Manners which can only be spotted by an eagle-eye viewer.
