i think kol will be killed, because in next episode they are going to find the cure...
Hahahaha is this raelly necessary?! Anyway,lemme try answering you! I dont think he'll be killed off...cause I refuse to believe that Klaus and by extent Rebekah would let tehir own brother be killed off..though they may not know Elena's plan...but I think Kol will be daggered or desiccated by Bonnie (Jeremy asks for Bonnie's help)..then Elena takes the white oak stake and hands it over to Rebekah the following episode (Into The Wild) and perhaps Kol will be revived when Elijah comes to town in 'Bring It On'
