Jaimie Alexander's (Jessie) role in this episode, and especially towards the end where she and Kyle go back to her memories, is nothing short of spectacular. I've never been so convinced and horrified by any episode of Kyle XY before that part. Even though the whole extra senses is pretty corny, I was terrified by the marks.
Apart from that, the episode was pretty lame, just like what Kyle XY seems to be lately. I think its canceling is spot on, because it's just not that good anymore.
So, all we have to do is wait for the next two episodes and hope that they turn out to be a sweet ending to Kyle.
