The Middle: Stormy Moon

This was an interesting episode.
Frankie (Patricia Heaton) is arrested, in her Sunday Best, as she was cleaning out the stove, for having an overdue library book. Brick (Atticus Shaffer) is oblivious, not even bothering to tell Mike (Neil Flynn) that she was arrested. Instead, after a dreadful day in the slammer, Frankie arrives home to see the whole family eating pizza. Naturally, she blames Brick for the overdue book and forces the whole family to rip apart the house to try and find it, but nothing comes up, though the family manages to get into an epic fight. However, though she begs to court to let her off, once the description of the book is read, the book wasn't checked out by Brick, because it is something similar to 50 Shades of Gray, so yes, Frankie was in the wrong. Still, the Hecks prove that they are bad parents because Brick checks out another copy of the book and reads the whole thing.
Sue (Eden Sher) is upset that Reverend Tim Tom (Paul Hipp) has a singing partner and dear friend, Reverend Tammy (Casey Wilson). She doesn't like change and is shocked when it turns out that the two are dating. But after they get into a fight, she realizes that she doesn't want Reverend Tim Tom to be unhappy and feels truly awful for pushing away Reverend Tammy's advice and praying that the two would fight. Luckily, Tammy comes back and the two start singing again. All is well.
Axl (Charlie McDermott) is excited that Cassidy (Galadriel Stineman) is back in town, but they don't talk really at all. Instead, they make out so Axl has some late nights. (Hasn't this already happened?) He wonders what is going on with them. At the end, right before she leaves to return to Vassar, she gives him a painting which she feels expresses their relationship and where it is headed. Axl graciously accepts the painting and pretends that he sees it in the same light as she does, but he doesn't. So all may or may not be well in that world.
Though this episode was better than last week's and there were some truly funny moments, I fail to understand how a person can be arrested for an overdue and lost library book, especially when it is only one of them. It would happen to Frankie, though, because she has the worst luck. And if you have Cassidy back, please actually use her. She had, like, six lines in the entire episode. And how long is spring break in Orson? Way longer than it is here, but whatever. At least I liked Sue's plot line this week, in fact, hers was probably the strongest this time, though Axl's was still probably the most realistic. Acting was great, though Mike wasn't given much to do this time, and there were some great lines this time around. Still, the show can do better. Grade: B+
Side Notes:
-When Cassidy finally calls Axl, he tells her that he and Sean (Beau Wirick) were just playing on his bed. Which they were, throwing the basketball around. He tells her that she can come over after the two shower. This was probably the funniest skit of the whole episode.
-Sue blames her bad teeth on Axl drinking all the milk, meaning Frankie was all dried up by the time Sue was born, causing gross looks on the faces of Axl and Mike.
-Brick blames Mike for coddling the milk sucker for the reason why he turns to books to be his friends.
-Brick tells the judge that he's doing better in the friend department. He stands near a few people and they don't move away.
-When Frankie is being arrested, Brick has his nose buried in a book but tells Frankie that if she's leaving to bring back cereal.
-Feelings are important people and you can't just sing them away.
-Okay, the big question, with all the time Axl and Cassidy are spending together, not talking, how far do you think they went? I haven't decided yet.
