At the close of the chapter, Mary takes care of Colin as her Ayah took care of her: she tells him stories and sings him a Hindustani song. This action implicitly positions her as both his caretaker and his subordinate, and foreshadows the way in which Colin will subordinate her on the narrative level by replacing her as the primary protagonist. Colin is the true master of Misselthwaite, and is Archibald Craven's heir; Mary, by contrast, is only a girl, and has no authorized position in the house to speak of.
The natural landscape is again depicted as conspiring with and mirroring its human inhabitants: it is the "wuthering" (howling) of the wind that awakens Mary and alerts her to Colin's crying. The sound of the wind seems almost to imitate Master Colin.
