Panel 1: A little while later, we find Elly telling Connie that having looked around the courtroom, she has come to the conclusion that the other driver isn't there. Since Connie has never met this person, she asks for a description.
Panel 2: I flash back to her coming with an inch of wetting her pants in sheer horror because Mike wanted to dress up as a punk rocker for Halloween when she gets all frightened as she describes the man as being greasy, unshaven, having long hair and wearing a leather jacket before summing him up as biker trash with probably a skull tattooed somewhere.
In short, he is tailor made to frighten a timid, ignorant woman who thinks that people who dress in a way that scares her are either bad people who want to scare her and destroy society or people reacting to a traumatic childhood. No one is allowed to dress like that because they simply like it lest Elly stand revealed as the panicky doughhead she is.
Panel 3: When they call for the man (a Mr Pervrett), he astonishes Elly by announcing his presence. She reacts by saying "That's him!!" because she wonders if maybe he beamed in from Let's Kill Suburban Housewives And Torch Libraries Land.
Panel 4: When he approaches the stand with his hair cut just so, his beard shaved off and his biker leathers replaced with a business suit, Connie tells Elly that she thinks they're in trouble.
Summary: If so, it's the same trouble Elly is always in: she's too stupid to anticipate something amazingly obvious and foreseeable like "legal counsel advising his client that he shouldn't actually look like a total fucking greaseball if he wants to be taken seriously."
