After the Mad Borg Invasion had ended, Paul and Angel were married in a chapel on Deep Space 5. Paul was pleased when the CO of the USS Courage, Captain Garek Darpeg returned and took command of the USS Impulse B. Captain Darpeg was half Klingon, but he was also half Vulcan and every moment of his life he was holding himself back from doing violence. Captain Darpeg actively looked for non-violent solutions which pleased Paul. Paul found himself drawn towards the Security and Tactical Departments and felt that was where he belong in order to Protect People. Paul was eventually was reassigned as the Chief of that Department.

Paul sees his wife, Lt. Commander Angel every time the Impulse gets back to it's home port inbetween missions. It is a strain to be appart for long periods of time, but it would be a step backwards in Paul's career to transfer to a Starbase, and it would be a step backwards for Angel's career to transfer to a starship.
The man who caused the brutal massacre that young Paul saw was caused by a evil Paul Williams from another timeline.
