Green eyed stone

I know, I was thinking that it was a little odd to that she is still calling him Kaleb after he said he prefferd Kol. When she and Marcel where talking in 2x08 I thought the writters chose to do it to higlight the fact that she saw him different as Marcel in some sort of way. Marcel reacted imidiatly by saying that his name wasn't Kaleb but that it was Kol and whent on how he was a liar and a manipulator and stuff. But now she is still calling him Kaleb, so I really have no idea why the writters chose to still continue with it but it doesn't bother me that much too.
