okay, so yeah, this is one of my favorite episodes of this series. it is totally awesome, first with the shocking scene of the playground shooting. I believed this first aired before the school shootings became more commonplace (as sad as that sentence is). and this was with children, i believe they looked like they were ten or younger for the most part. and all of that happened so fast, and the reactions the doctors had to working on these children... especially dr. catera who had to work to save the shooter's life... even after her actions killed a little boy. that was amazing. it also brought back memories for kate of killing the man at the cabin... it ended with her realizing that she actually needed to deal with it.
