6.16 The Tangible Affection Proof (Feb. 14) in Season 6 Posted February 19, 2013 Sheldon has to be changed slowly since rapid development of the Shamy may disturb the fan base the most. The writing team has to please two large constituencies, the fans who like him as the asexual Wack-a-doodle and the growing Shamy romantics. i'm still not sure how they will pull this off but they are going to have fun trying over next two or more seasons. ya know, I don't think that explanation by Sheldon about his problems dealing with the physical aspects of relationships was just his answer to Penny's question. It also signals the writers have permission to develop not only the physical aspects, but also the emotional aspects of his character, no matter how slow that may be, over the next few years and the fans should anticipate this.
