I can see that Sheldon's unsettled; was it seeing his mother having sex(part of the science route was to counter his mother's religious moralising), was it realising that, it's also what Amy wants, the death of Prof Proton(his science grandfather), or the horrible realisation that he's wasted his mental powers. But we also have Amy unsettling him. He was always a bit skittish, and had several minor meltdowns. But he seems to have lost all his bearings, and lost faith in everything that made him unique.
