Damon: You do anything physical for that person to see that he is yours.
Stefan: You go away from the situation to cool down.
Klaus: You go somewhere where you can be alone and cry it out.
Elijah: You try to ignore it, knowing that Elijah would end the conversation if there was anything being hinted by the other person that meant more than friends.
Kai: You tell you nearest friend about it to get it off your chest.
Matt: You don't really get jealous cause nearly everyone has been with Matt and doesn't want him anymore.
Tyler: You pull him aside and talk it out right then and there.
Jeremy: You pull the break up card. Even though the last thing you want is for you and Jeremy to break up, it gives you a sort of power you crave in that situation.
Alaric: You will most likely break something or cry.
Enzo: Like Elijah, Enzo sould never do thaqg to you and you know it. So, you try to just let it go.
Kol: You talk to his brothers about it. They eventually tell Kol who/what happened to make you feel jealous.
