Fitzstephen appeared with Becket at the council at Northampton Castle, where the archbishop was disgraced. When Becket was then forced into exile, after refusing to sign the Constitutions of Clarendon, King Henry II accepted a petition, in verse, from Fitzstephen and pardoned him from the banishment meted upon his master. When Becket and the king reconciled, Fitzstephen became his administrator once more. Fitzstephen records that he was among those of Becket's advisors who cautioned against excommunicating king Henry. Fitzstephen was with Becket on the day of Becket's assassination in 1170.
