(Strip Number 4621, Original Publication Date, 29 May 1986)
Panel 1: As she and John turn in for the night, Elly tells him that she isn't exactly sure if she's ready to read her poetry in public.
Panel 2: After all, she could panic, she could freeze up and she could make a fool of herself.
Panel 3: John starts out saying something supportive by telling her not to worry about any of that.
Panel 4: When he makes a not at ALL helpful comment about how she's survived making a foolish spectacle of herself, her worry mutates into rage.
Summary: Given that we're about a few days away from an unfunny, condescending and stupid crack about her joining the hysterical society, it's blazingly freaking obvious that Unfrozen Caveman Dentist John is being as supportive of anything that takes Elly away from her proper and sole role of cooking his food, cleaning his house and keeping those horrible children from bugging him as he always is. It's equally obvious that Rod did something to irk Lynn.
