Did You Know?


The killer tells his mother that she is "out of Heparin" when checking her pillbox and then tells her it is "the one for your heart". Heparin is administered by injection, intravenously or subcutaneously. The "pill form" is a drug called warfarin. Furthermore, while it can be used for heart surgery patients, it is not considered a "heart pill". It is an anticoagulant so he would tell his mother it is "the one for your blood". See more »

Danny 'Danno' Williams: It's Halloween, we're supposed to go trick or treating. She says "Dad, is it okay if I go with my friends instead." What am I supposed to do, huh? What am I supposed to do? Say "No, I command you to spend Halloween with your father?" It doesn't sound so bad, I should have said it.
Steve McGarrett: [Trying to get rid of Danny] Hey, want some candy?
