Directed by Danny Sharron, “Hold Me in the Water” is as seamlessly, thoughtfully inclusive as “Dark Disabled Stories” was. At the top of the new show, after Haddad’s dramatic entrance on a lift through the stage floor, and his ebullient greeting — “Hello, darlings!” — Haddad gives visual descriptions of the set (by dots, the design collective) and himself (costumed by Beth Goldenberg). He notes the projected supertitles, the dimmed but not extinguished house lights, the audience’s freedom to pop in and out. (“I’m begging you,” he says, “if you need to go to the bathroom, go!”)
