Well, someone's right to freak out will be defended.
Panel 1: Liz asks Elly if any more RSVPs have come in. Elly says yes but they're missing about ten.
Panel 2: Liz then whines that she hopes they respond soon because she wants to tell Annie Nichols how many meals she has to prepare.
Panel 3: She then hypocritically bleats about people waiting until the last minute which causes Elly to tell her to calm down.
Panel 4: Bridezilla roars that she can't causing Elly to look like a weird, horrified female amalgam of John and Weed.
Panel 5: John, having heard the bellow of the monster his wife unleashed in her mad quest to turn Liz into her, asks Elly how things are going. She tells her freaked-out hubby that her patience is almost gone.
Summary: Once again, we see Elly being unable to deal with the consequences of her actions. She raised a child who viewed a BFW as all-important, despite protestations to the contrary, and she's pissed off because she got yelled at. If John is smart, he won't pull the same stunt he did when April asked for five minutes time to save her files before eating. If he does, he's liable to have his head bit off.
ETA: Lynn must be pet-happy right now. Instead of photoshopping her characters at their many beach trips to tell us that it's summer, she used yet another pet strip.
