We all saw that Jeremy & Elena killed Kol in order to discover the map quickly and get rid of Kol who at the time seemed as a threat. However, he could supposedly be bought back to life as it would seem that he died on the behalf of raising Cyrus. As it is known, if you died on his behalf you will be ressurected from death. Meaning Kol's fait lies in the hand of the gang or supernatural squad. If he is ressurected the will question are:
Wil he come back as an Original Vampire? You're dead when a vampire so could be ressurected into a human.
Will he attempt to kill Elena and Jeremy?
Will his attitude be unhightened if he goes back to being human?
How will react to Elena and a new change of lifestyle?
Wil he forget everything leading Elena to invite him into her life and social group and he eventually falling in love with her?
Will he threaten Bonnie into turning him into an original again?
If Cyrus is bad will he help get rid of him or would he run away?
Could Elena love him back due to her being annouyed of Damon controlling her and Stefan sleeping with Rebekkah?
If he is ressurected I hope he becomes a series regular and doesnt go onto the spin-off as I think there is still a story to picked up with him in it in The Vampire Diaries. There is a certain reason he was chosen to dis-like what the gang was trying and wanted it to stop. The creators knew what they were doing when they picked him as it leaves a large amount of questions behind.
WHAT DO YOU THINK OR WIISH WILL HAPPEN TO KOL?
