But Kane and Undertaker werent always on the most amicable of terms, as we saw in the summer of 2010. After accusing Rey Mysterio of attacking the Undertaker, Kane challenged the ultimate underdog to a SummerSlam showdown. He vowed to not only win the match, but to lock Rey inside a casket in a symbolic act of revenge. True to his word, and having picked up the victory, Kane went straight for the casket. While Rey managed to stall him at first, he wasnt so lucky the second time. But then again, neither was Kane. http://www.dailymotion.com/video/xegsx6_kane-vs-rey-mysterio-2-2_sport When the Devils Favourite Demon reopened the lid, he was greeted with quite the surprise; laying there inside the casket was none other than the Undertaker. What made this return a special one was the way it displayed the Deadmans uncanny ability to adapt and keep up with times. Going for a David Blaine-style casket trick was a neat way of maintaining an air of supernaturalism, without compromising believability entirely.
