- Just why does Missy bully Sheldon so much? Why does she want Sheldon to be miserable and lonely all the time? Sheldon hardly even acknowledges her presence and she's always out to get him.
- It isn't easy having a sibling who's vastly more intelligent than you, especially when they're an Insufferable Genius to boot. So, she's partly jealous, partly sick of him being such a smug, condescending know-it-all.
- She might be jealous that Sheldon is mom's favorite for all his academic achievements and high profile as a child prodigy. Though all Missy does at home is watch TV, eat candy and be incredible rude to her family (including Mary) so of course Mary prefers Sheldon over her.
- Ever have a sister? If yes.... there's your answer.
- Probably a mix of these. Sheldon's a very demanding kid to look after, and dealing with his needs takes more time than Mary and George spend on Missy and Georgie. They went on a spontaneous road trip for Sheldon. This on top of Sheldon's general attitude. Of course Missy's going to be more inclined to act out, since their parents barely take any notice of her outside the usual routines. She's got to get her digs in against Sheldon when she can, like ratting him out about the Watchmen graphic novel after Mary catches her with a Cosmopolitan.
- If Tam said that the Americans were the "wrong" side of the Vietnam War (which I highly doubt given the oppressive Communist regime of Vietnam is guilty of numerous human rights abuses), why did he run away from Vietnam to live in the United States?
- I've just watched this episode; Tam said that the Americans were on the "wrong" side of the war from the point of view of the Vietnam government, which is why Tam's father was sent to a re-education camp. "My father was sent to a re-education camp because they (the government) said he fought on the "wrong side" of the war.". So Tam himself doesn't think this.
- Missy told Sheldon, "You only speak one [language]" as a means of bullying him in "A Stunted Childhood". Actually, many episodes shows that Sheldon clearly knows Spanish and he earned 100% on Spanish vocabulary quizzes in elementary school as shown in "A Math Emergency". That means Sheldon knows at least two languages. Why doesn't he tell Missy off that?
- Why is Sheldon good at acting in Young Sheldon but loses the ability completely in The Big Bang Theory?
- The implication is that Older Sheldon would be capable of acting if he'd just take the stick out of his ass long enough. As he aged his ideas about what a certain type of academic (and genius) became more set, and therefore his prejudices solidified. There seems to be a large element of anxiety involved too, as part of the end of that school play episode so the memory of that informs his character too. Most of the problems and character growth achievements Older Sheldon goes through in The Big Bang Theory involve either loosening him up or reframing the situation to suit his worldview.
- Same reason his friend didn't attend his wedding - Continuity Snarl.
- As the emotional gap between Sheldon and his peers grows, perhaps he draws himself into pop culture like Star Trek, comic books and video games, as well as his eventual career in physics. By the time we meet him in the Big Bang Theory period, or at least the flashback when he and Leonard first met, his whole world is science and pop culture, and has been living away from his emotional touchstones enough he's not as human as he is in Young Sheldon. Time and time again his anti-social habits and air of superiority alienate people, to the point where he has to be coached to behave in a socially acceptable way.
- Why does Missy have a lower-pitched voice as a child than she does as an adult?
- Missy's voice as an adult is still fairly low pitched for a woman. Though if you want a reason for it, studies have shown that speaking with a higher pitch comes across as being more friendly and appealing. Missy is very much a social butterfly and thrives when she has attention, so she could have subconsciously adopted a higher pitch because of this.
