Marilyn and Simon absolutely break my heart in this episode, with the look on her face after he tells them his parents don't care when he goes to bed, and the look on his face when he says goodnight after she talks about "our kids" and is obviously including him in there, too.

Oh my God, this! He just says it so matter of factly (because obv he wouldnt know the diffence) and she's like, so sad and awkward and stunned by the sheer horribleness of that. And the big smile when she kisses him goodnight, oh my GOD. I'm like, at least partially in love with Marilyn Teller in this episode.
