Chosen answer: The main cause of her death is not specifically stated in the show, but Howard does mention that she passed away in her sleep. The cause of her death may have been something relating to her weight problems.

Casual Person

Answer: She had cancer.

Answer: No, you didn't miss anything. The writers never say who got tenure. (Although, as a side note, the entire process of getting tenure for the characters is entirely wrong in real life and none of them would have got it).

Answer: There's several factors that mainly revolve around Amy never having any real girl friends growing up (she had never even been to a slumber party). Also, she never had a girls night out before and would rather do that then hang out with boys. She was only going to the movie because Sheldon was going, but had no real interest in it. She also wants to spend as much time with Penny as possible.

Chosen answer: Penny's reply was "wait, you're inviting people to our wedding?" Most people don't like when other people invite guests to their wedding. Penny and Leonard were getting remarried so their families could attend this time (and a few friends). Mary, Sheldon's mother, is not family to Penny or Leonard, and while they like her, they wouldn't consider her a close friend. I think Penny liked the idea that Mary was hooking up knowing how it would bother Sheldon, who didn't realise what was happening. And it was funny to her knowing the conflict it could cause since it didn't affect her at all.

Chosen answer: It's unlikely that they ever met, which would mean Mary visited. However, the show seems to imply Leonard has had to call her in the past to help out with Sheldon, and he has her number. Plus, Mary seems to be more motherly (then say Beverly) and one can assume she's called Sheldon a number of times to check in on him and it's likely Leonard answered the phone some of those times and spoke to her. Given that Leonard often shares personal stories with the gang, it's also likely he's told the gang something about Mary.
