As graduation day approaches, a worried Casey is having difficulty writing her valedictorian speech, which she blames on her fear of Derek pulling a prank and ruining it until Derek points out that she's actually afraid of what the future holds. Meanwhile, Edwin is concerned that he won't be able to live up to Derek's reputation at J.S. Thompson High when he goes there in the fall. The family celebrates Casey and Derek's high school graduation and the two make a very awkward announcement: that they are going to the same university.
