Panel 3: Why is Elly saying "peel peel peel xc"? Yeah, I know she's not saying it, but it looks like. Why the unnecessary onomatopaea in the first place, and why is Liz in the kitchen in her robe?
Panel 4: Well, duh. Actually, that's a neutral statement, so I can't comment until I know what conclusion she's drawing.
