to turn it back on is always a person's choice. in Elena case, she didn't want to have her switch back on. Stefan n Damon tried to forced her by trying to induce some feelings.

Tho I almost agree on everything you said, you make it too obvious when you said the show plot were good from season 1 to early s4. Guess to you, it was starting to suck in ep7, wasnt it? :D

Don't forget, to turn it back on is always her choice. it depends on her if she wants to turn it back on or not.

guess it's becoz stefan put a mask of sad face and teary eyes while damon prefer to put his usual "i dont give a shit" mask.

or she could just snap the witch's neck. LOL.
