One of Georgie’s biggest trauma’s is experiencing a dead women walk.

Then years later, Jon get’s blown up and goes in a coma for six months, and yet despite all rational medical science he jumps up from his bed good to go. Not because he’s miraculously okay, but because he submitted to the same fears that brought a cadaver into Georgie’s life. And in an episode that’s titled “Zombie,” for that matter!

So with all that in mind, I think Georgie’s distance from Jon in later seasons makes perfect sense. He’s a dead man walking, and that makes his existence both a representation of the worst thing that ever happened to her, and a contradiction towards the “everything has an end” lesson her trauma engraved in her.
