SPOILERS FOR "Misery Chick" * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * I was watching "Misery Chick" again, and I noticed that, aside from Daria and Jane, Mack was the only Lawndalian to stand up to Tommy Sherman, even a little. It's obvious from his initial reaction when talking to Kevin that Mack remembered, and hated, Tommy Sherman. And in the scene where Tommy is putting Kevin down, note Mack's expression ... he's *glaring* at Tommy. He also told Tommy directly that what he was saying wasn't funny.
I think Mack's a rather under-rated character, because of the show's focus (on Jodie only as a friend of Daria's, and on Mack only as Jodie's boyfriend). Observing his behavior in that ep, I can easily see why Jodie likes him, and why Andrea may have a crush on him. He's quiet about it, but Mack's definitely the kind of guy who both in fiction and IRL might be a "hero". He's smart, strong-willed, polite, and principled.
Sincerely Yours, Jordan
