(Original Publication Date, 16 April 1991)
Panel 1: Liz continues to tell Mike that as long as she's in her mad wall, there's nothing he can do to bother her. It would be as if he didn't exist. The end result is the sort of sullen leer that quickly mutates into the blinding rage we saw last June when she dared to tell him to apologize for calling her mean things.
Panel 2: Since he will not be silenced and since she has no option but to endure his weak bullshit because HE WAS HERE FIRST, he reminds her that all he has to do is rip it away (as he is about to do right now) and she can assume her rightful position of abuse sponge. She knows this.
Panel 3: When he asks her what she'll do if he rips the box away, she tells him that she'll just put an invisible wall.
Panel 4: As he perpetrates the garbage move of tearing the box away so he can be a repulsive choad, she says that invisible ones are stronger than ones that he can see.
Summary: Mike's problem is very simple: he doesn't know how to treat people and he's not interested in learning how to do so. A smart person would do something akin to apologizing or cutting the malarkey but that ain't him. He's the dick who wanted to attack Molly for teling him that she didn't need to be dogged by a ten year old. He's the assclown who wanted to straight-up murder Liz for being told to apologize. He sees himself as a victim of people who play games with him and mistreat him cruelly by asking him to consider how his actions make them feel. He's bad meat in a can.
