twinkle

I sit across from him and notice the twinkle in his eye is gone.

With a twinkle in her eye, she recalls one groom who was confident he could make it through a reading, only to nearly collapse in tears at the sight of his bride.

"It's his laugh, right? He has such a hearty laugh. And sometimes you'll see that twinkle in his eye, or that smirk, and I just get transported."

He performs with an affectionate twinkle in his eye, offering understanding even when his jealousy is put to the severest test.

But this is transformation in a relative twinkle.
