As sneaky as Matthew has tried to be, Deacon has anticipated his arrival at the clinic where Albertine is being held; both children are now under lock and key. But with the help of Chocky, guiding them to join their minds as a gestalt entity, they are able to escape. Just as Deacon tries to block their way out, they call upon another power to repel him, joining minds with children the world over who have encountered Chocky.
