Home of Rhett & Link fans - the Mythical Beasts!
Jason has not made any appearances on the show since he left except in GMM 1000 when he congratulated them. However, R&L did appear on his show Geek & Tea (which came out right after it was announced he was leaving (which was in this GMMore))
I'm pretty certain Jason never dated Jen. In this episode, R&L talked about how Jason had a Canadian girlfriend. Her name's Ashley & they got married last year!!
That's all I know.
