Can I put the real hospital in it?+
Describe it on the board, from the ward to the view from the window to the vending machine, and it's drawn in the look. The people in it are drawn from photos only with their permission.
What do they get?+
A finished issue downloads as a narrated video with music, or as its panels in a zip with the captions, and you can share it by link, so it reads on a phone from the bed.
Can it keep going while they recover?+
Yes. Give the writer another idea in the comic desk's ideas box and the next issue is drawn with the same cast, on whatever schedule you set, until they're home.
