Hooray for continuity! Jon calls Ellen again, last heard from on April 23.
It's kind of cool that we can't be sure if Ellen is lying, or Jon is so horrid that he causes instantaneous migraines. Either way, this time Jon "gets" what's going on. His wilting enthusiasm is funny, but these episodes are so much harder to take when Jon ends up angry, sad, and self-loathing. It doesn't help that he's shown concern for someone's well-being in panel 2.
Garfield is also harder to take when he takes special pleasure in Jon's defeat. Certainly the reader doesn't need Garfield to explain the joke, and the awful cat is just rubbing it in.
And this time Jon's back-fat is utterly out of control.
