That whole doppelganger being meant for each other thing is total crap and I'll go to my grave complaining about it. If anything, it seems the universe (Tessa? is that you?) has it out for them and enjoys torturing them.
Wasn't Tessa the one who sort of created the whole doppelganger destiny thing. I may be remembering this wrong (which is entirely possible as I tend to tune out when the show goes into its long exposition/narrative scenes) but I always thought Tessa manipulated that whole thing, based on what she told Stefan of her back story. And so I always thought the point was that the doppelgangers would never be happy.
That basically that was her way of punishing Silas and Amara, century after century. I mean think about it, Tessa was a bitter, vengeful psycho. The woman stayed bitter for 2,000 years. In what world would she create something that allowed Silas and Amara to be together, even if it was in doppelganger form. So I think the point is that the doppelgangers are fated/destined or whatever, to never be happy. Something will always ruin things for them. That this was basically Tessa's way of punishing Silas and Amara for all of eternity. Man, I miss the psycho nut.
