I was reading in the Carlisle character forum that some people have the theory that Esme was Carlisle's 'singer' before he saved her. I think that would be a very interesting dynamic! The reason for the theory is in Midnight Sun, when Edward tells Carlisle that he has to go (to Alaska) and Carlisle asks why: "Has any one person ever smelled better to you than the rest of them? Much better?" "Oh." The only problem with the theory is that Edward would obviously know if Esme had been Carlisle's singer from reading his mind, and the way he phrases his question doesn't suggest that. But, he could also have been struggling so much in the moment (In the line before, he tries to ask, and stops, then trys again) that he just didn't say, "There's someone, for me who smells like Esme did" which would be the logical statement if Esme had been Carlisle's singer. I don't know. I just thought that it was such an interesting idea. Probably not true, but, the what if is fascinating.
