Never Swim Alone (THEATER) Two men—once childhood friends, now adult rivals pretending to be friends—face off in a game show broken into 13 rounds: “Power Lunch,” “Business Ties,” “Who Falls Dead the Best,” etc. Their competition is scored and refereed by a young woman, a ghost from their shared past, and she takes unholy pleasure in announcing that one of these men has a gun. The acting is good and the script is great. This is what WET does best—tight, tense, and funny little plays that aren’t boring.
