Well regardless Kane just out of nowhere wins the IC title from RVD who had gone through all those matches unifying it with other titles and then Kane just loses it at the ppv, which I think was the weekend after Kane won the IC title, and the IC title is gone.
I just realized it's quite silly that we're even arguing over whether Kane buried anyone or not since the main point was it was all so HHH could unify the IC title into his since he thought he was "above" the IC title.
