Darth Blacknainous tells Good Vader that he means to avenge himself upon him

"What is the meaning of this attack?" Good Vader demanded angrily. "Where is the crew of the USS Indomitable?"

"Surely I have made my meaning plain!" Darth Blacknainous replied calmly. "I mean to avenge myself upon you, Good Vader! I have deprived your ship of power and, when I swing around, I mean to deprive you of your life! But, first, I want you to know who it was that had beaten you!"
