    The Penny being a spy theory was actually suggested in the show by Sheldon. I can&apos;t remember which season it was in or exactly what Sheldon said. It was when the crew were working on the differential equation app. Sheldon said something like &quot;Imagine a beautiful woman befriends three geniuses and their friend Howard. She waits around until they come up with some brilliant idea that she can steal. Why else would she being always hanging around with us?&quot;<br><br>That theory gets some traction with the group. They all begin to doubt.<br><br>If Penny was some government spy she didn&apos;t really have to have developed feelings for Leonard. She could have been ordered to marry him to keep him close.

    Penny wasn&apos;t a resident when the elevator accident happened, so Sheldon wouldn&apos;t have any reason to try to get her and Leonard together by blowing up the elevator.

    I always thought that Bernadette had ADHD and got on Adderall, which has a history for making people more competitive and aggressive.

    Bernadette was forced into beauty pageants by her mother, who she described as very competitive and aggressive towards other contestants and strict with her AND she had to take care of all her little siblings, which was so bad that she didn’t want to have kids herself for a long time. She was a parentified oldest daughter + used for her mothers gain + had to deal with her weird and checked out cop father. It wasalways very clear to me that she just opened up more and became herself towards the rest of the group.

    Howard letter was one of the most emotional moments in the show, although any moment where Sheldon and Howard weren&apos;t messing with each other and were genuine was a peak moment

    He&apos;s more emotional intelligent in Young Sheldon because it&apos;s being written by &quot;present&quot; Sheldon at his most evolved point and he&apos;s either consciously or unconsciously editing his past.

    With the elevator theory, i thought you were going to say that the theory was that Sheldon messed up the formula on purpose so that he could then save Leonards life. Leonard says in that episode that the reason he has put up with Sheldon for so long is because he saved his life and then kept his secret for him, which is weird because Sheldon is supposed to hate keeping secrets, especially big ones like that. It could&apos;ve been his way of making sure Leonard felt indebted to him, which in turn made his life a whole lot easier considering everything Leonard did for him, he didn&apos;t want to risk Leonard giving up and moving out.

    My theory is the reason why George wasn&apos;t seen as a dead beat dad in young Sheldon was because Sheldon one didn&apos;t one his father to be seen in a bad light or two it was a coping mechanism. So that&apos;s why instead of Sheldon finding his dad cheating on his mom in the spinoff was because it was Sheldon trying to cope of the things he saw as a child.

    My personal favorite theory is that Sheldon DID get an autism diagnosis but his mum was like, one of those that then doesn&apos;t tell their kid about the diagnosis and is like, &quot;You are completely normal and I love you&quot; not in a denial sort of way like some parents do, but in a, having autism is completely normal for a human being and this is how God made you and I will love you despite the troubles you bring me, way
