Eight episodes into this first Matlock season, with a long holiday break ahead before we get the next episode, this show has made one idea abundantly clear: Lying ain’t easy. Matty Matlock has to remember every piece of the backstory she created for herself when it comes up conversationally — like in this week’s episode, when Olympia asks for some advice about Julian’s philandering, given that Matty’s fictional dead husband, according to the lore, was a cheater.
