The premise sounds like a setup for “Reviving Ophelia: The College Years”: a young woman is sent to therapy after she writes a sexually explicit essay for freshman comp. But first-time playwright Ellen Fairey focuses instead on the two young men who (improbably) observe the therapy sessions through a two-way mirror–one of them a psychology grad student, the other a film student running the AV equpiment. Though both fall in love with the girl, Fairey’s two-way mirror is less a tool of voyeurism than a symbol of her characters’ inability to connect. Serendipity Theatre Company’s faintly desolate production–dimly lit and performed with an air of quiet desperation–suits the piece perfectly. Through 2/18: Thu-Fri 8 PM, Sat 5 and 8 PM, Athenaeum Theatre, second-floor studio theater, 2936 N. Southport, 312-902-1500, $10-$15.
