No, Johnny didn't promise his father anything, but now his father has gone on to explain it further, making it seem like Johnny has much less of a choice than he previously thought. In P.T.'s mind, there is only one correct choice.

Yes, Jayne seems pretty set on the idea, at least at this point. As for Ophelia, just because she doesn't have someone else in the picture, doesn't mean that this will always be the case, or that she couldn't decide to just be alone for a while. Of course, I'm not saying that any of this will happen, but these are all fair possibilities. There doesn't have to be another person in the picture for a relationship to end. As for Tank, Ophelia was never interested to begin with, and now he's really gotten himself into her bad books. That would be an interesting twist for Johnny, though...

Those questions were just meant to get you thinking. Of course I know. *wink* I'm not going to tell you just yet, but what seems more likely?
