Darth Conqious tells Good Vader that he needs more lightsabers

"I want more lightsabers, Good Vader! Many more!" Darth Conqious said. Then, he turned to one of his minions.
"Those who killed my father have escaped!" Conqious told his minion. 'Track them down."
The minion obeyed his master's orders and set off to track them down. Conqious then turned back to Good Vader.
"I will kill them!" Conqious said.
Then he left.
