I had this idea of Godric, after meeting the True Death, having the choice between fading into nothingness (= hell. No, God is not a sadist who rost his creation if they fail him. He just erase them.) or to go back on Earth as a human to atone for his sins ( see: milleniums of slaugher, being a vampire for dummies).
So, of course Godric choose to go back! (and maybe run into Eric in the process. Make me want a fic for this made by someone who agree that "2000 years of faith and love" is the slashest canon-remark ever!!!! :D).
Here's what he would look like with a bit of color on his face and a real hair-cut:
