First of all, I haven't read any spoilers about the character (other than that she was Stefan's love interest and blah, blah, blah), so feel free to post anything about her (with proof) that will weaken or verify this theory.
Could it be that Rebecca is related to Katherine (and the original doppelgänger)? The thought came to my mind when watching the preview of Stefan saying, "who are you?, and Katherine had a way of mesmerizing men by being somewhat mysterious so perhaps that's why Stefan became interested in her.
Well, there was this theory that Bex is Klaus' sis.
IDK, I guess we just have to wait and see ...
No. Hope not. That would mean she would stay longer.
And becky is one character i pray to gods gets offed past. even her character description gets at my nerves.
Also, we didn't miss each other! :D
She's that chick that was in that disney production with the mermaids right?she's pretty..
Klaus' sis, that would be interesting, especially if Stefan did something to her and she wants revenge for it and therefore Klaus will bring Stefan to her :) But I can't remember if we've been told that she's still alive (she should be since she's a vampire but who knows).
But her character is very irrelevant to me. I don't like the actress playing her very much but I hope it gets better :)
