I read an interview that it was their intention for Myka's storyline to span more episodes but when they got cut down to six-more-and-that's-it, they decided to end it, otherwise the last batch of episodes would've been kind of a downer.
I could have used a refresher myself, I had totally forgotten the stuff about Claudia's sister, I couldn't remember why she was all ticked at Artie.
Rebecca Mader popping up in this episode as Lisa deVinci was neat, her character was funny. And she was nice, I had quickly grown used to her being evil from her Once Upon a Time and Fringe appearances.
