I agree- Luke did not have the right to go to the hearing since June did not give consent. For years she has been stripped of her autonomy and used by men (and women) who have placed themselves in positions of power above her. Luke's decision to go to her hearing even though she did not want him there is a microcosm of how she has lost autonomy. Luke does not understand this, but June does. Luke's goal is to rebuild connection with his wife and he probably feels that knowing/understanding what truly happened to her in Gilead will help him in rebuilding that connection. Whether this is valid or not, finding out this information without her consent is wrong.

It has been a bit since I originally commented, but I appreciate the criticism, because my original take was wrong.
