Siblings

“	THIS SOUNDS MESSED UP... BUT... I'M PROUD... OF HIM???	„
	~ Papyrus on his brother Sans.

“	Kaine came down here to get away from the insanity of Spider-Man's world. But then he put on a costume and fought crime anyway. He wanted all the power, and none of the responsibility. But he took it on anyway. He found a home here. He had friends here. A city that counted on him. And while he may not have liked it... turns out Kaine is every bit the hero that I am. Wherever he is... I hope my brother has found peace.	„
	~ Spider-Man talking about his clone brother Kaine's activities in Houston.
