Jon rolls out the front door, and back in again after his date. The creepy part is not that Garfield has not moved over the course of several hours (he's barely moved over several years, after all), but that Jon is sliding around the house in a blissed-out love trance. Garfield can always tell how Jon's date went, because Jon is so expressive he either looks happy or like he's been hit by a train.
So again, the unsettling thing is that Garfield can normally count on Jon sharing all sundry details of his date, but Jon, driven to distraction, isn't speaking. In a way, he doesn't have to: the onset of twitterpation is one of the times the world can not only read you like a Denny's menu, but the world doesn't probably care to. Here is probably where Garfield's world will "change forever" (as we were promised by ballyhoo on garfield.com when Jon and Liz started dating. Garfield, rather than being glad for Jon, is disgusted with his idiotic, face-mutating grin. But do we sense something else? I think that undercurrent is not simple jealousy that Liz is taking up Jon's time, but not wanting Jon to be happy. Because Garfield likes to make jokes about Jon being a loser. Because Garfield has a perception of his friend that he wants Jon to live up to. Because Garfield needs a victim, an abuse object. And Garfield needs someone who needs him. That may be so he has the opportunity to withhold or dole out affection as he wishes, but it is endearing nonetheless.
Fan Edit Suggestion: The same story could have been told using only Panel One, and the last two frames. This would have preserved Garfield's determined lack of scenery, but robbed us of knowing how much Jon and Liz love seeing ill-attended movies after filling up on twin helpings of meatloaf.
