I feel very sad for Tara and her situation; no one deserves to be lied to and deceived the way she was. This is a person whose heart and passion for giving far exceeds most and is the least deserving of pain in her life. Whoever she ends up with will be a lucky man.
Drew also went through a ton of personal growth. I feel very strongly that Drew will find the person he is looking for, and that through his heartache, he will be better equipped to identify who that person is now that he knows himself so much better.
