Ciaran McConville's new play looks at love in different forms. A brief series of video extracts top and tail the acts, but there's no precise consensus. What's in no doubt, though, is that Tom loves — and feels responsible for — his autistic brother, Alex. Since the death of their mother, he's put his life on hold to care for him while their sister goes to uni and then embarks on a career. When he bumps into her former classmate Mary, another devoted relationship develops — but love can't protect any of them from fate. Sam Hazeldine's Tom has a gentle reticence, balanced by Katherine Manners' almost too bouncy Mary, and Karl Davies impresses as the blossoming Alex. McConville sounds a further cautionary note that caring can be taken too far when their doctor drives his trophy wife to drink by blurring the distinction between patient and family friend.
