Reason why - there could be more than one at play. Domestic finances? More interesting to me at the moment, is how their decision to return is now affected even in the last month since their return by wider events involving his two uncles - namely Charles Spencer and Andrew. For instance, if his purported desire to "reconcile" with his father is genuine, then what's his reaction to his uncle Spencer's book of accusations? What's his reaction to Uncle Andy's court case - after all, him and his wife are besties with that man's daughter? Will he run back to SoCal if RAVEC rules against security for him or not at the level he wants? Any of his reaction to that in a wrong way could easily demolish his purported desire for "reconciliation" with the King...if that was even genuinely wanted in the first place.
