Did any of you notice the little rhyming game going on between Garth and Lilly?

When Lilly and Garth finished their first howl together, garth sees the Eastern pack and says: Oh no, you better go. Then Lilly says: But no one has to know! Then Garth says: Please, just go, now! Then Lilly finally says: Oh no! hahaha! I lol'd at this!
