from KLantis:
A destined fight rages on between two warriors who possess the same blood. Rock keeps Kain busy by wielding the techniques that Terry taught him the past few years. But Kain laughs and suggets Rock that he can't win if he doesn't summon the evil power sleeping within him. Rock shouts that he is nothing like his father, and maintains his stream of attacks against Kain. But Kain is no pushover either: his purple flames of death are more than enough to blast Rock backwards several times. Kain was some fighter! As Rock begins to think if his efforts are futile, the image of his dying mother, his father giving him the cold shoulder, and Terry raising him like if he were his own son, begin to burn in Rock's mind. Right then, Rock just flips the lid, and unleashes a huge aura of evil energy. Kain is dumbfounded, and the mansion trembles to the stones. Then, Rock performs a technique which Kain had only seen once...done by Geese himself! But this move was way more powerful now...and with a impressive series of blows, Rock smashes Kain into submission, and causes havoc in the mansion's structure.
at least, it pretty much shows that Rock was the one who brought down the mansion.
Rock link you posted was fuking hilarious, especially the part where a drunken Terry told Rock about his dad.
