Indeed! That really surprised me. Interesting! And yet we've seen pretty much zero interaction between Denise and Lisa, and you'd think with all Lisa's issues Denise would have been working her in a big way. Perhaps Denise is a tad starstruck?? And if Penner didn't figure it out on his own, perhaps that's why we never got the big reveal/payoff I was bemoaning earlier in the season. Once he knew, he realized oh yeah that's her, and just started talking to her about it.
