If Elena becomes a vampire the salvatore boys might not be interested in her any 더 많이 because once 당신 become a vampire all your emosions are heitend they will probably wait a couple of years until a new doppelganger from elena and fall in 사랑 with
her(sorry didn't fit)
There's not going to be a new doppelganger. Elena didn't have a baby before turning into a Vampire. I didn't get your 질문 though.
As NiazAbedini & clairmxxx already siad, there' won't be another doppelganger, Elena ended her line (if we won't suddenly learn that she has a missing sister 또는 close cousin.). 당신 should explain what 당신 mean with your question, becasue this 질문 really isn't clear... Why wouldn't Salvatore brothers be interested in Elena when she'll be even 더 많이 in 사랑 with both of them...?
yes once 당신 turn into a vampire your sences are heightened. But that just means that elena human emotions will be ten times stronger. So elena would still feel what she felt when she was human just those feelings would be heightened. The salvatore brothers would still want her.
