In Beauty and the Beast (2017), there is a knowing look at the end between Mrs. Potts and Maurice who does a double take back at her. What was that about?
It's a moment that comes from the original animated film.
Basically, Mrs Potts fancies Maurice, and lets him know it with a look.
Maurice's double-take is him going (in his mind), "Mrs Potts seems to like me... wait, what?!"
It was a little more obvious in the original animation, with the look being one of mutual appreciation. A lot of people picked up on it.
