A potential plan

"This problem is incapable of being solved though usual psychological methods," Cerebrum noted, writing something on his pad as he and Rufus appeared in his office, a few months before the present date.
 
"To hell with psychological methods!" Rufus shouted.
 
"That's one way of putting it," Cerebrum said, rummaging through his desk. "With a tad more hostility than most, though. Why do you think you're being so hostile?"
 
"I'm being flipped back and forth through time, and my companion is bloody nutter, what do you think?"
 
"You're hardly in a position to comment on my sanity," Cerebrum stated, continuing to search through his office. "After all, you came back in time to murder your father."
 
"Only as a last resort."
 
"Still, you put everybody you knew from your present time at risk, as well as messing up the time-space continuum as a result of your actions. You can't predict what ripples will occur and what they will affect, but you did go back. And you have the nerve to call me nuts."
 
"You are! It says so in your personnel file."
 
"I'm being treated and you're not. That's the difference Ah, here it is," Cerebrum pulled a key card out of the desk drawer. "The firing key for the meson cannon. I was wondering where it went, it disappeared a few months ago. Right out my locked desk drawer too."
 
<Tick>
 
"Now where are we?" Cerebrum noted. There were a few shots and laser blasts. "Ah, it would appear we're in a gunfight in the future that's just outside my office. Look out, duck!"
 
The future Cerebrum pulled his head back inside his office as a shot from Dean came by. It deflected off the door frame, flew over Rufus' head as he dropped to the floor, bounced off the wall and headed back. There was a smack and a scream as it impacted with someone. Cerebrum reflexively reached down and grabbed a gun that had been dropped.
 
<Tick>
 
"Well, that must have been painful," Cerebrum noted, as they appeared back in the present. "Still, at least the future Dean won't have to worry about unemployment. The position of ship's eunuch was unfilled the last I heard."
 
(Hey, it was an accident. :)
