Okay so if Isobel gave birth to Elena, and Catherine supposedly found Isobel after she turned, how is it possible that Elena looks like Catherine? Unless Isobel was lying and in fact Isobel is also a doppleganger it's just she looks like Catherine at an older age?? Sorry I got my bff's into this show and they're now just as addicted as I am and we're going through the seasons. Now that I'm watching things over again for the second time I'm having more questions haha!! I have watched all 5 Seasons but I honestly don't remember every thing about every episode. Thanks in advance for any help!!
