Character comment in S4E8 (via @TrueBloodMame)
Godric gave a comment during Narnia scene:
The ability of a vampire to feel what humans call love diminishes rapidly through the years. The closest an older vampire such as Eric comes is in his relationship to his progeny, but that, too, does not quite approach what Eric is feeling right now. The elation is contagious: to be happy with another person—human or vampire. I hope that Eric and Sookie can enjoy this moment, then embrace it, and hold on to it forever. And not worry about what will happen when this spell eventually breaks and Eric returns to his old self.
