If he was missing or in a coma it would explain the room the MC discovered in his drunken state having a 'shrine' like importance to her with the items of possession there and her opening the door to it almost like she wished he was there or something. I accept your opinion on it but considering how much story still needs to be done, I'm not sure DPC will elaborate a lot on it either way. I think we can agree that he'll be indisposed for most of the story and won't suddenly barge in the bedroom demanding Bella explain how she slipped, fell and landed on MC's dick.
