Undertaker is back you facing Triple H?

After this segment between Triple H and John Laurinaitis you were getting a little boring because they were just talking about the time a bell rings and the arena goes dark and paralyzed and get back to play another stroke and The Undertaaker is back in WWE ! Triple H was in the ring and very confused and when Undertaker entered the ring looked at the sign and Wrestlemania 28 Triple H stared at and and Taker gave him a pat on the shoulder and left the ring and immediately began to hear the boos to see Triple H and saw how they would repent and would return to the ring to talk to Undertaker, but did not stop and continued walking and left the scenes, after which incidentally Undertaker slightly changed the look and rang his music and seeing the ring was the sign of Wrestlemania 28, but rejected the challenge Triple H the question now is: Triple H accepted?
