Kol is the older brother of Rebekah. He seems to be a year or two older than her. Since Henrik died, they are the youngest Mikaelson siblings.

Kol is protective of Rebekah as it is seen that he even stands up against Klaus to defend her, though he never says that out loud.
Rebekah seems to know Kol better than anyone. She can tell when he is being sincere and knows what he enjoyed as a human, such as his favorite holidays. Like Klaus, Kol does not like any of Rebekah's lovers and seems to dismiss them whenever he comes into contact with them, especially Damon, Marcel and Matt. Though he already hated Marcel for taking his place in the family.
Rebekah and Kol bicker constantly, mostly because they are the closest in age, and Kol has made fun of her love life, but despite that, it is shown that they do love eachother and are protective of one another.

Rebekah really wanted to help return Kol, and when she realized that she had no choice, but to return to her body, she thought of her promise and knew that she could not help Kol as she wants. Knowing that the only chance to return Kol will have to use to revive Esther. Rebekah was crestfallen that she really wanted this to be used to bring back her brother. But Klaus did not leave the choice to Rebekah, and she had together with Elijah crank out a plan to deceive Davina, and replace the Kol's ashes, with the ashes of Esther.
