Alan Tracy: Hey, Dad. That stuff the Hood said, about you leaving him to die. He was lying, right?
Jeff Tracy: No. See, you can't save everyone, Alan. It doesn't matter how hard you try or how brave you are. It doesn't even matter if it's someone you love, someone you'd give your life in a second to save. You just can't save everyone.
Alan Tracy: What was Mom like?
Jeff Tracy: She was a lot like you.
Teacher: Mr Tracy. How kind of you to come back from outer space, Alan. I trust re-entry wasn't too rough.
Lady Penelope: Oh, and England won the footbal last night.
Parker: YES! EN-GER-LAND.
Alan Tracy: So, do you still think that science can explain everything?
Fermat: Not girls.
Brains: Fu-fu-nno way.
