The 2017 San Diego Comic Con "Supernatural" panel was one for the ages.  A surprise concert, a 360 format, and lots of jokes at the expense of Misha Collins.  Great times!  We have the highlights from live tweets by Nightsky on the WinFamBusiness twitter and Fangasm SPN.  Spoiler alert!  
 This is what was reported from the Spoiler TV liveblog (Spoiler alert!)
Kansas performed Carry On My Wayward son before the panel started.
Mashable has a video of the Kansas performance and a write up of the panel.
Richard Speight, Jr. and Rob Benedict hosted the panel.
The theme with Jack will be Nature v Nurture
The boys will be divided Sam thinks Mary’s alive, Dean doesn’t. Sam makes it his mission to get Mary back.

Jack may be the key to getting Mary back
