She has emphysema. I'm not sure if that comes across well. She made a joke. No one found it funny. Emphysema is not a laughing matter. Our last mention of Alex's mom other than the last two pages can be found here.
I quite suddenly did not feel well in the middle of making this page, so I kinda just tossed it together so I could go crash. The important stuff is there.
Note to self: probably add some filler page or panel of them taking their seats when getting ready to print for book.
