Those arent for Sheldon Cooper.
Hes a man of science, and one who struggles to understand social cues and norms.
At the heart of that change is Sheldon Cooper, the man most resistant to it.
Hes grown a lot across 11 seasons.
Hes still obnoxious and selfish, but hes learning to be better to the people around him.
Instead, this is about as straightforward asThe Big Bang Theorygets, and thats a good thing.
Its a good thing because it allows the characters, and the marriage, to take center stage.
With a Saturday wedding all planned and ready to go, Penny is running point and keeping everyone organized.
Doing so isnt all that easy, especially when parents are involved.
Before the wedding can get started though,The Big Bang Theoryhas to set up two surprises.
Returning Bark Hamill to his owner is a dream come true, but the interaction doesnt end there.
Hamill wants to pay Howard back somehow, and thats when he comes up with an idea.
Everyone arrives on the special day, and emotions are running high.
Leonard tears up while helping Sheldon with his boutonniere.
Ill always be your problem, says Sheldon when Leonard mentions that hell legally be Amys problems now.
They joke, but theres sincerity in there.
The back half of The Bow Tie Asymmetry is filled with these types of sentimental moments.
Hed be proud of you.
Im proud of you, says Mary.
Leonard gets wrapped up in it too, seeing the massive potential in Sheldons breakthrough.
Thus, its up to Penny to once again wrangle everyone into position.
Sheldon and Amy come to a realization.
They have their whole lives to do science together.
The reality of what theyre about to do sets in, and its beautiful to watch.
What The Bow Tie Asymmetry does in its final moments though is question that exact sentiment.
The old Sheldon Cooper would have seen meeting Mark Hamill as the highlight of his entire life.
Amy is everything he could have wanted, and everything he didnt know he wanted.
After Amy delivers vows that a tearful Mark Hamill calls surprisingly moving, Sheldon delivers his.
He has no words though, for the first time ever.
Hes going to put actions above words, and for Sheldon Cooper, thats a huge deal.
