-Aela asks you to search for the plans of some Silver Hand's members.
-When you came back,you ask she for a new job, she will tell you to go with the old man.
-The old man will ask you to take the witch head (Blood's Honor Quest)
-When you came back you will notice the Silver Hand attacked Jorrvaskr and Valkas will ask you to take some revenge (Purity of Revenge Quest) and bring back some fragments stolen.
