how grim feels about Max's room and how it smells?

Why does Grim feel the need to protect the house?Edit

Grim feels the need to protect the house because Max's dad is on parole after being in jail for killing Max's mom. Grim is afraid that he will come for Max and kidnap him. Also, he is in charge of the house and if Kenny Kane invades the house, he will feel guilt. He doesn't want Kenny Kane to kidnap Max.

Why does Max promise to stay in the house?Edit

He promises to stay in the house because Kenny Kane was on parole, and Grim and Gram thought that Kenny would come for Max.

Where does the phrase “Cross My Heart and Hope to Die” come from?Edit

I think that it mainly has to do with King Arthur and how he talked with his nights.
