Locks of Hair

When Catherine died, I really liked the gesture of puting locks of hair in her locket. I thought it was interesting that Heathcliff replaced Edgar's lock with his own because it shows how deeply in love with Catherine he was. It didn't matter to him that she would never see the lock of her in her locket but he wanted to connect with her at a level beyond the mortal world because he cared so much for her. I liked when Nelly combined the locks of both mens' hair and placed it in the locket.
