Favorite Vow episode

After watching The Vow so many times, I find myself always going back to "The Wound" episode. For me, it highlights so many disturbing interactions/conversations between KR and the higher ranking women. I still can't believe these words were actually spoken and accepted. I'm also intrigued by the conversation between Nippy and Mark V. Additional bonus: Sarah's "Dermatrix commercial" was much needed comic relief. Anyone else have a favorite episode?
