"Scorched Earth" still haunts me. The Kids that Riley save and give back to their parents... dying in the Nuke blast was just brutal. I have listened to that episode several times and every time I think the kids are going to get on the chopper, and it never happens.

The attempted rape on Lizzy is the opposite for me, every time I hear it I get a little sick thinking Lizzy is going to be violated and have a uneasy relief when Scratch saves her.

What scenes still freak you out?
