Meanwhile, Katie has some unanticipated news of her own. Her renewed relationship with Rick is developing, but everyone wonders what's going on. Is Rick about to break her heart again, or could this be something lasting?

As the time draws closer to the wedding, Todd and Christy face differences between them that might make married life more complicated that they thought, and Christy wonders if their relationship can work when put to the test.
