TVD 3x22: If Klaus is still alive, did Tyler die या is her just in some one else's body?

After long deliberation, I've come to the conclusion that Klaus's body possesion of Tyler is the same as his possesion over Alaric's when he was first introduced, and Esther's when she took over Rebeka. Therefore, I'm going to say Tyler's concious is still in there, but he is asleep while Klaus has his body.

Remeber when Klaus possesed Alaric in season 2.
He needed a witch,this time it was Bonnie, it's exactly the same thing.
