Actually, a spoiler comes in to play.
Panel 1: As Elly takes a phone call, John reminds her that she has to go because everyone else is ready. She tells him to hold on a second because her brother Phil is on the line.
Panel 2: She asks him to repeat what he said as well as his location.
Panel 3: He, Iris and Georgia are at the hospital because Jim had yet another heart attack brought on by the fatty foods Flapandhonk stupidly feeds him. He thus won't be coming to the wedding.
Panel 4: Iris will, of course stay with him and he and Georgia will be right over. He then tells Elly not to tell Elizabeth about this.
Panel 5: After all, Jim wouldn't want to spoil her big day on his account. Too bad Elly's day is spoiled. I guess we won't spend the last week watching people kiss her ass after all.
Summary: BOXCAR!!!!! This is the monkey-wrench they talked about on CC. If Iris and Phil think Liz is going to stroll down the aisle not knowing about Jim's troubles until after whatever honeymoon she goes on, they've really lost it. She's going to spend the rest of her frakking life feeling like something somebody scraped of their shoes because her big day was one of his last. Crap. The Settlepocalypse will be the Deathbed Wedding of Ultimate Doom.
