Lie To Me - Killer App

Like the Social Network, this story centres around a socially-inept young man who also happens to be a genius who makes a social networking system, along with two friends.  One of them, the female, comes to see Foster and Lightman as she is worried she is going to be shut out of the company because the leader has already shut out the third friend.  The girl knows Foster because she was a patient of hers when she was a child.  Everything goes to hell when Foster finds the girl stabbed and rapidly dying.  All the evidence points to the third friend but in truth, he and the girl were lovers and were planning a take over of the company and shutting the genius out.  Lightman confronts the genius who starts to hack into Lightman's personal internet accounts and the work servers.  They eventually trick him into proving he had accessed private emails and confessing to killing her, which Lightman records and puts on the genius' own social network!  Lightman and Foster organise for him to get transferred from prison to a mental institute.  He thinks that is better, till Lightman explains that DR Foster will be administering drugs to him that will destroy his mind for good.  The episode finishes with Lightman's daughter asking if he truly loves Foster and he agrees he does.  She asks what is holding him back, but he doesn't know the answer to that.
Believe it or not, that is the very last episode of Lie To Me.  Unless we get a change of heart from the network and it gets a reversal but at this stage, no season four.  I can't believe this is how it ends.  It is a great episode but I am actually a little sad that I will no longer be seeing these characters again.  The acting was exceptional and the writing was intelligent.  This was one of the few brilliant television shows out there.  Such a shame to see it go.  I want to go on record to say that this was one of my favourite shows and I loved it.  Would have liked to have seen Lightman's and Foster's relationship develop over some more time.  Such a waste.  Thanks anyway to all the actors and crew for bringing this show to life.  Thanks for the entertainment for the past two and a half years.  You will be greatly missed.
P.S. I loved the way Lightman works out that the girl had had sex before she was murdered.  Brilliant!
