This data basically comes out of the OT II theory pack, but it cannot be properly understood until the individual gets into OT III. So there is not also a Confidential OT II article on the state of Clear.
Charge has been getting released from the B/Cls all through the lower grades as well as auditing actions after that.

He is still able to be influenced by other beings in his vicinity, and he can still get confused as to who he is.
