This evening of new works features Daniel Reitz's "Napoleon in Exile," a tender, very funny short play about a young man "on the spectrum"; Neil LaBute's compassionate, morally complex "The Mulberry Bush," whose park-bench confrontation between strangers echoes "The Zoo Story"; and Albert Innaurato's "Doubtless," a slapdash spoof replete with cursing nuns, orgy-hosting priests and diatribes that don't make good dialogue (1:30).
