Sick and Bell

Intro
The "Sick and Bell" plot is when a character gets injured or sick and must be watched over by one of their friends. At some point as they stay over, either they outlive their welcome and become a nuisance to their caretakers or it's shown that they were faking being hurt for so long or the entire time and could have left earlier.

Plot Sample
Guy gets into a terrible car accident he survives but the other driver does not. However, he's broken both his legs in the crash. He cannot afford to go to the hospital, so he waits until his friends Hugo and Ava come around and take him to his house so he can stay and heal. As his legs are broken, Guy can't walk around and get things on his own, so he is given a bell he rings whenever he needs certain services. At first, Guy uses his bell for practical reasons, like he wants Hugo to fetch a glass of water or Ava to make his lunch, but then as the days go on, Guy just uses the bell because he can. At this point, the plot diverges down two paths. One is Guy annoys Hugo and Ava to the point where they kick him out, and the other is where Guy accidentally shows Hugo or Ava that he was healthy for longer than he appeared to be, either that he healed some time ago or that he was never injured that badly in the first place (despite having his legs broken), thus resulting in Guy being kicked out of Hugo and Ava's house.

Examples of Sick and Bell
SpongeBob SquarePants - Can You Spare A Dime?. After quitting his job at the Krusty Krab thanks to Mr. Krabs suspecting he stole his special first earned dime, Squidward goes homeless, losing everything he owns (except a new bum outfit which is ironically more than what he typically wears). Being the Saint he is, SpongeBob lends a hand to Squidward, saying he could stay for as long as he wanted until he was employed again. After months pass, Squidward runs SpongeBob into the ground and horribly tires him out to the point of SpongeBob wanting Squidward to GET OUT. Eventually, One morning, SpongeBob has a heated conversation with Krabs that ends up with his first dime, a prehistoric-looking torus, falling out of his pants, evidence that Squidward didn't steal the dime. This relieves SpongeBob greatly as it means Squidward won't have to freeload in his house any longer.

Steven Universe - House Guest. After being injured, Steven's dad Greg is invited to stay in the temple while his leg heals. As Steven and the Gems have to work on a mission, Greg repetitively misuses his warp whistle that Pearl gave him and said to use only when it's absolutely necessary for the four to return and tend to his needs. When Steven goes out to get his dad some donuts, he remembers he forgot to ask Greg what donut he wants, so he enters the temple again to see that Greg's leg was fine.
