Calvin was horrified what this… evil… thing… had just done to his best friend. But Calvin didn't cry. Calvin didn't give up. He didn't let Hobbes' sacrifice be in vain. Instead, Calvin did what most grown-ups wouldn't do in this situation. He shouted, "GOTTA CATCH ME FIRST, YOU RUSTY PIECE OF SCRAP METAL!" Now that's guts. Now that's courage. Now THAT'S friendship.
Vlad: You wouldn't turn your back on an old friend, would you?
Jack: An old friend? No. You? Yes.
