I have another possible theory on this. What if that person is entering the cabin to get a shovel to dig out The Undertaker? It could be a return for the Undertaker but the person who dug him out is Sting. Sting and Taker vs Kane/Barrett at Mania works so well if they did it right. You what's crazy. WWE had a back up plan for Taker which was a tag match that was The Corre vs Kane and Taker as a team. Kane is the one that beat him and buried him alive and that is the plan they have. So dumb. That is my other theory on the video that they showed on Raw. I would love to hear thoughts on it.
