I was swithcing back & forth from ER, so I didn't see all of it. The two missing teenagers were found, one alive, one dead....and since I wasn't watching it that closely, I couldn't figure out which one! The show didn't explicitly say...just showed the two moms waiting at the end of that hallway and their faces as Jack is walking towards them.)
agnes!
PS - Didn't Lynn Whitfield do a great job as Jack's hard-nosed/kind-of-nasty supervisor? (At least I think it was her.)
