I , just thought I would post my take on the episode. As far as killing Per went, I don't think any of them could have done it, no matter what the boy grew up to be. It's not that none of them have never killed before but Per was a kid and most people, are hard wired to protect kids. Only a monster like V.S. would kill a kid. Kendra's flash backs looked to me, I may be wrong, like time filler. Ray's maybe being a father and the angst he was having over it only showed one again that Ray is a good man, or tries to be. Rip's angst over Per and in the end not killing the boy showed that Rip may not be a cold as he thinks he is. I loved the scene where Rip all most calls Sara his assistant the changes it to body guard. Having Mick and Leonard beat the crap out of each other was inspired.
All in all I thought this episode could have been better but it could all so have been worse. And as for trying to kill V.S. if it was me I would just bury the SOB alive in several feet of concrete. Won't kill him but it will keep him from causing trouble till he digs him self out in lets say 100 or so years.
