This debut play about a boy growing up autistic and queer has plenty of theatrical wonders. Writer JJ Green, who also plays Boy, depicts the hard realities of his character’s childhood but alongside there is a world of mermaids and starry skies that he believes in just as much. That parallel world interrupts reality with sparky humour and magic in Bronagh Lagan’s production. He can romp across the universe in his mind’s eye, Boy says, but “just don’t ask me to make eye contact”.
