The men of McKinley may be back together, but as we know full well, it's not at all smooth sailing in the Big Apple. Especially in matters of the heart -- and between the sheets. Artie, Sam, Kurt, and Blaine were all reminded in different ways that "love is a battlefield" -- set to an all-'80s soundtrack, of course.
For instance, it turns out that since settling into his life in NYC, Artie has been every bit the player, hooking up with several girls at film school -- except the one he really wants, Julie. In the process of getting with the others, though, he finds out he has contracted chlamydia. Ewwwww. Seeing him dressed up throughout the episode as a big STD, though? So funny.
