Also, here's my plot bunny/prompt since I just finished reading this epilogue. Which was way too short!! You must start writing again soonest!

Sam goes to Washington. Runs into Jack O'Neill. Who has been asked quietly by Sheppard to look into finding Sam, because he wants to help Dean. Sam hooks up with SGC SG1 and ends up traveling on the Pegasus to Atlantis for a mission. One that involves rescuing SGA SG1 and not knowing that Dean is a part of that team until much later. Throw in a little Cas if you can.
