Amara seeing the first Silas' doppelganger thinking it was Silas himself coming to save her and set her free then the pain of another person crossing over went through her body except this time it was the face of her beloved
To people like my friend who say Stefan being friends and falling in love with Bonnie wouldn't serve any narrative purpose - Qetsiyah, Silas, and Amara.
Qetsiyah and Silas were close/best friends before they got engaged. Amara was Qetsiyah's handmaiden (or a favored slave if we're honest given the time period). Both Silas and Amara betrayed Qetsiyah. Not only did they steal her immortality potion, they betrayed her trust on her wedding day (side tangent, how did these idiots expect the most powerful witch of their time to react? Because Silas was powerful, but even he needed Qetsiyah to create immortality), ans are then portrayed as more innocent or undeserving of suffering (specifically specifically Amara who was NOT an "innocent woman" in this situation).
Now we have Bonnie, Stefan, and Elena. Stefan goes for Elena immediately due to her looks and contrast with Katherine, Elena learns nothing of him and even when they get closer, are they really? Bonnie was in the prime position to become his best friend and Plec ruined that because she's racist - I digress, back on my what if concept. So they become friends, at first because of Elena and then regardless of Elena.
The shit that happens can be kept, but now Stefan doesn't just seek Bonnie out because he wants something, he seeks her out because he just wants to. He starts falling in love, blah blah blah, the Delena crap starts up, fast forward and Bonnie realizes she loves Stefan and maybe they don't hook up immediately, but it's THERE.
Meaning, we get a mirror of sorts - because Bonnie would ALSO get more traits from her book version and thus be a bit unhinged like Qetsiyah (Bonnie McCullough wants to be choked to death and no, that's not an exaggeration).
And beyond that, can you imagine the DRAMA of it all? Silas being confused as hell by Stefan not only priorizing Bonnie over Elena, but getting clocked by Bonnie as not being Stefan? Qetsiyah thinking Bonnie's setting herself up only to witness Stefan choosing Bonnie over Elena. Elena being the one who gets "betrayed" in the scenario of "my lover chose my friend over me" in whatever convoluted plot the season would follow?
Yes, it would have served a MAJOR narrative purpose.
Betrayal
Qetsiyah, Silas and Amara
I've seen it in the poems and the sands I've pleaded with the powers and their plans I tried to rewrite it, but I can't It's the history, the history of man
I get it, Amara suffered and blah blah blah.
NO!
You're the handmaiden of THEE most powerful witch, you know her intimately, you KNOW how she'll react to being betrayed - no one can tell me Amara had no idea the lengths Qetsiyah would go to make her and Silas suffer.
My friends saying crap like "she was a sweet girl driven mad" and I'm just - no she wasn't, she was a homewrecking idiot that thought the man she got with was powerful enough to protect her from Qetsiyah's wrath. Silas legit had to seek out, trick, and steal from Qetsiyah for immortality be possible, how was he going to protect Amara from Qetsiyah's wrath?
"But she loved him" - and acting on that "love" was counterintuitive to NOT SUFFERING A FATE WORSE THAN DEATH! And yeah, you're immortal now, but come on! She MADE true immortality BY HER OWN RIGHT, you can't be dumb enough to not think Qetsiyah would find a way to make you suffer for betraying her.
And on Silas, dude wasn't shit either. Again, he had to trick and steal from Qetsiyah to become immortal. Beyond that, he was her best friend - are you really going to tell me he didn't know exactly how Qetsiyah would react to being betrayed? Or at least have an idea? You can't tell me he thought she'd be a crying mess incapable of retaliation or that she'd never find out where he and Amara were hiding. Like, SHE made immortality possible, it stands to reason she can unmake it or do far worse. The fear of that alone would've kept anyone with a brain in line!
my headcanon about the doppelgangers is that they always gravitate toward each other not romantically exactly but they feel a pull that makes want to be in each other's orbit that's why Katherine immediately went after Stefan when she saw him and even tho Stefan was compelled at some point into a relationship with Katherine and by all rights her face should disgust him after what he went through he still fell in Elena's orbit, we see them almost going back to it when Stefan lost his memory
so if according to Elena and Alaric, doppelgängers are considered supernaturals, that's how when Elena killed Alaric he was brought back by the Gilbert ring, so by that logic is there an army of doppelgängers on the Other Side???
Silas and Amara.
