How we cite our quotes: [Part.Paragraph]
Quote #1
"I'm from somewhere else, like [Alice]." (2.484)
This is when Ma reveals that she used to have a home outside of Room. The fact that a home can be a place other than Room is still incomprehensible to Jack. Heck, Jack can hardly believe that there are any other places besides Room, whether they're homes or not.
Quote #2
"It's the real world, you wouldn't believe how big it is. […] Room's only a tiny stinky piece of it." "Room's not stinky." I'm nearly growling. "It's only stinky sometimes when you do a fart." (2.520-2.521)
Room is a place of captivity for Ma, but it's Jack's home. Because he's so attached to it, he defends Room when Ma insults it… and he insults her back as a form of revenge.
