OMG YOU GUYS YOU GUYS YOU GUYS I JUST REALIZED SOMETHING!
In the scene where Gaston manipulates Lefou into lying about his attempted murder of Maurice, Maurice is watching the entire time… but he doesn’t get angry at Lefou at all. It’s Gaston he’s furious at. He tries to hit Gaston and not Lefou even though Lefou just lied. Maurice knows what’s going on!!!
