“For me the nail in the coffin for SE was last episode. Stefan used one of the WORST moments in Elena's life AGAINST her...just to GAIN the UPPER HAND on Klaus. I'm not even going to get into what he did and how I feel about it or even compare it to what Damon did in 2x20. But I get why he tried to do it(he DIDN’T HAVE TO do it, he could have RETURNED home at the end of 3x09 and not plot his REVENGE against Klaus, keeping everyone SAVE IN THE FIRST PLACE. He WOULDN’T have to save them if he hadn't did this) he had to make Elena's fear believable. BUT HE COULD HAVE EASIL SPED the car AEOUND ANOTHER ROAD and fed her his blood BU no he had convince her he was going to KILL her on the BRIDGE where SHE almost DIE and her PARENTS DID. It was CALCULATED and PREMEDITATED, as if he was trying to HURT her in the most emotionally DAMAGIAG way possible. I said I wasn't going to compare this to Damon's actions in 2x20 but I guess I lied: Damon's actions can't be justified but I understand why he did it. He LOST control and fed Elena his blood RECKLESSLY and on IMPULSE. That's the DIFFERENCE between what Stefan did and what Damon did. Stefan thought out what he was going to do, he PLANNED IT. Damon (though I don't condone it) LOST CONTROL and FORGOT about the consequences of his actions for a few BRIEF moments. Another difference between what they done? Stefan did it to GAIN REVENGE...Damon did it to SAVE Elena's life. So yeah, I do think SE have been ripped to shreds and their 'epic' story is no longer so epic and loving. I'm sure”
