So Uryu was declared the heir to the Quincy throne. That means currently he is classified as a bad guy. May be Kubo is using him as a double agent and he is secretly giving info to Ichigo. But what if Ishida is actually on the bad side? What if all his moves till now have simply been to examine Ichigo, his possible opponent in the future? What if by working for Ichigo, he intended to collect information. Also no one knows the true reason Uryu's father gave up being a die hard Quincy. What if that reason has something to do with this? All these questions will be answered but we will have to wait till then.
