So I’ve been thinking a lot all day about this whole “the mark needs to be fed” thing and I’m wondering if being a young demon with the Mark of Cain is sort of like being a baby vamp in True Blood. In the world of True Blood the older the vampire, the less they need to feed. If you’ve watched the show you’ll know that there was a character named Godric, and he was over 2,000 years old. Near the end of his life he said he required “very little blood anymore” and I always got the impression he hadn’t fed on a human in a very long time.
We don’t know how old Cain actually is, but we have to assume a couple thousand years at least. So I have to wonder if his age was a major factor in his ability to stop killing once he met Colette, or if the power of love is just that strong. Not only that, once she was gone he was able to throw the first blade into the deepest ocean and live a quiet life of solitary bee keeping, keeping his promise to stop the killing. Does his mark still need to be fed? Or is he simply so old the urges are no longer an issue? Has he somehow learned to control them solely because of his love for Colette, or do the urges become less intense over the years?
There’s no way Dean will be able to keep the mark and live if he’s not a demon, he won’t be strong enough, but before he’s cured completely, if he is “patched up” temporarily by human blood or angel grace or some combination of the two, the mark will still be an issue. He won’t die from the urges because he will still technically be a demon, but I assume the mark will still need to be fed even then. So, will the power of love have to come into play early on? Or will his young age as a demon result in the urges being too overwhelming to fight after a while?
