Ryan's Song

When Lisa feels guilty for not telling Ryan that he's adopted, she agrees to help him pursue Tessa. Lisa's generosity leaves Ryan believing that he must be dying of "Ryan disease." Meanwhile George and Dallas go on their first date, but in her nervousness she invites her life coach, Tabitha, to join them -- which puts George off -- and Tessa agrees to babysit for Opus while Noah and Carmen attend an opera.
