Sheldon and Amy's wedding is just days away, with all their friends handling everything for them so that they can focus on what they need to. Something unexpected happens to Howard which affects the wedding in a way that Howard hopes will please Sheldon, but may irk someone else with a key role in the wedding. Much of what the friends need to do is to attend to the needs of the Coopers and the Fowlers who are all arriving from out of town. Those needs are great, especially by Mrs. Cooper and Mrs. Fowler, their wants which may threaten to overtake the festivities. Meanwhile, Sheldon and Amy can only think of something else, all stemming from Amy's comment to Sheldon that in tying his bow tie, it should be asymmetrical and not symmetrical like he is trying to tie it.

Penny Hofstadter: Now, we got a lot of family coming in tomorrow. I'm gonna need everyone's help. Think of this as one of your comic book movies. There's a bunch of superheroes, each with a different task.
Raj Koothrappali: Oh, like the new "Avengers".
Bernadette Rostenkowski: Which one was that?
Howard Wolowitz: The one you slept through last weekend.
Bernadette Rostenkowski: [fondly] Oh, that was a good nap.

Why wasn't Leonard's Mother at Sheldon & Amy's wedding?
10 February 2019 | by msprgoSee all my reviews

Can anyone tell me why Leonard's mother wasn't at the wedding?? Was it mentioned on the episode? I just thought her absence was strange since they always kept in touch. Maybe I just missed the mention, but I couldn't find an answer anywhere else on line.
