Miraculous Ladybug/Fridge

Fridge Brilliance

 * Stormy Weather: How did get Mireille get out of the frozen elevator? Well, Ladybug's Miraculous Ladybug Healing Wave could have fixed it and she managed to get to safety.
 * Alternatively, assuming the elevator was defrosted but still broken, the fire department could got her out (we see them trying to get Alya and Manon out).
 * The Bubbler: Of course Hawkmoth/Gabriel avoided being taken. Not only is he the puppet master, but his lair is in a room hidden from prying eyes and outside of the one he controls, doesn't seem to have any windows.
 * Mr. Pigeon: Aside from being a Butt Monkey and the scene just being funny, of course Jean wouldn't mind being a door slammed in his face three times! He's the butler of the Bourgeois', he's got to have a lot of patience to deal with them and has probably dealt with worse.

Fridge Horror

 * The situation Aurore goes sounds awfully like grooming. She's in a bad position, so an adult man gives her an outlet for her and she temporarily doesn't know the wrong she's doing or how to give up the privileges he gives her without outside help. There's also the fact he is calls her 'my Weathergirl'.
 * Thank goodness Ladybug and Chat Noir stopped the Bubbler. The bubbles going into space don't paint a pretty picture for the adults/imprisoned students. Either the bubbles can make it into space and the adults/imprisoned students die from no oxygen or the bubbles can't take getting out of the atmosphere and pop, sending everyone to their deaths!
 * Mr. Pigeon: His allergy is played for laughs, but still Adrien/Chat must've been suffering when all those pigeons carried him off.

Fridge Sadness

 * The Bubbler: There's a decent chance those pens from the last three years weren't actual gifts from Gabriel, they just so happen to be things Nathalie kept on her desk and not wanting to disappoint Gabriel she gave them to Adrien and passed them off as gifts from his father.
