Over in the treehouse, Kevin is holding up a sheaf of receipts and irritatedly asking Lucy if she entered them in the chequebook. "Oops!" she says, and I guess she's going for cute, but it's not working. And he crabbily points out that "oops" won't cut it when one of them bounces a cheque, and she says she thought they have enough money in the account to cover any bounced cheques, and since by definition you bounce a cheque when you don't have enough money in the account, that has to be one of the stupidest things I've ever heard out of the mouth of any adult, and he lectures like you would a child (but considering what she just said, maybe it's warranted). So she takes the chequebook because she has a few other entries she forgot to make, and she kisses him on the cheek, which he says won't work on the bank. "Are you sure about that?" she says, and thankfully their "flirting" is interrupted by Ruthie's clomping up the stairs, like THANKS FOR INVITING YOURSELF, and Ruthie is halfway into the apartment and flopping all over the table before she even bothers to ask if she's interrupting anything. When Kevin says she isn't, the little hellspawn actually ROLLS HER EYES before coming over to ask for Lucy's help in getting her to the party of Unknown Parentage, and she takes a really really really really long time explaining why it's so important that she go to this stupid party. Lucy says she'll talk to Annie, and she's sure they'll be able to work something out. Ruthie thanks her and leaves, so Kevin decides it's time for another little lecture, and says it sounds like Lucy herself just gave Ruthie permission to go to the party. Lucy doesn't think so, but that she's confident she'll be able to convince Annie, and that her parents will probably call the Rogers parents or drop Ruthie off at the party. "I wouldn't get in the middle of it," says Kevin, and how interesting that he's lecturing Lucy on butting in, but to do it he has to butt in himself. Hmmm. "But what I do know, I'm the idiot who thinks you should balance the chequebook." SHUT UP, KEVIN! GOD!
So Cecilia is bringing Sam and David, the Wonder Twins, into the kitchen, and Annie's all, "Where've you been? You've been gone for hours!" and the twins say, "It's a surprise! For you!" but Annie has to make them not actually spill the beans as to what this stupid surprise is, and maybe she might want to ask Cecilia about keeping the twins out for hours without Annie's having any idea where they are. Nope, she just invites Cecilia to supper. Makes sense, I guess. Cecilia deserves some kind of reward for taking the twins out of Annie's hair for the day.
