Incest!?!

On the episode the livers wild, where he gets really DRUGGED!!!

He is talking to his mother in the after life I suppose. I mean what does that mean, they were in the after life, she would FOREVER be hanging out in the wreckage of the plane she crashed in. what kind of after life is that.

But at the end they are talking and I sort felt a little tension. I didn't think it was sexual. She says "thanks" walks over to him and does a small kiss on the lips. So i mean it wasn't a smoocher, but it seemed more than just a mom and son kiss. i mean doesn't the mom usually just kiss the son on the cheek. I thought that showed motherliness and caring. So what does a very gentle slow kiss to the lips mean.

and this was on fox. I'm so confused.
