When Q asked us why the trial would be delayed for a year, I think it's because Maxwell was co-operating and they were creating unsealed indictments and possibly grand juries. The fact that she didn't even bother to testify says to me that she already had already negotiated the outcome in return for her co-operation. However, anything is possible as we don't know what's going on in the background but I believe the White Hats are definitely in control.
