Not sure what is happening in that last gif, but Gaston seems mildly concerned.
I think the last gif is amazing because this is our chance to see him actually care about someone else besides himself (or Belle). Notice how he looks down when he says “WOAH! Careful”. It’s like he’s hoping no one is watching him worry about another one’s safety. GASTON YOU’RE A SWEETHEART.
AND I DIDN’T THINK I COULD BE MORE IN LOVE WITH HIM.
I WAS SO WRONG.
