!Lisa calling Becky as soon as she learns of Costello's condition is really forcing the story along. We were getting rid of Becky when lo and behold Lisa calls her to give her details of his condition shortly after learning about it. Right in the nick of time! So even after all the issues with Carla surrounding Becky, Lisa is keeping in close touch with her. Is Lisa this emotionally connected to Becky that she had to call her as soon as? After all the crying we had to endure from Lisa she does this as if it was urgent that she contact Becky? Sloppy writing!<
