The Bitterness of Being Left Behind

(SEASON 6 CONJECTURE) Drama ensues between former lovers Kitty and Artie. My conjecture as to what happens when he returns to McKinley and they encounter each other a year-and-a-half after their breakup. [ Based upon some early spoilers for season 6, set during the episode Homecoming (6x02). Written months before the episode aired, so it varies quite a bit from the aired eposode. ]
