- As shown in the episode "Baked with Anti-Love" in case of emergencies, such as when his wife Rebecca had a stress-induced panic attack after people turned into jerks due to her cursed pie during the competition (thanks to the anti-fairies), she almost passed out from it. Stuart luckily had the medication to bring her back to her senses.
