Something I just noticed..
after re-watching the finale...
Ryan invites Cassie to dinner, then proceeds to tell his parents about his "exciting" new job and enlists their help in looking for a rental apt or office space in Chicago.
However..this was after he had known about what the real estate mogul was doing (i.e. bringing in the Java Hut and kicking Cassie out of her retail space).
So, why in the world would Ryan invite his parents and Cassie(!) after he knew what had happened.
