Elisa says "I can't believe I was carrying an empty revolver" as she is re-holstering her semi-automatic.
Wrong gun type.
Nokkar had been on Earth for centuries, but he did not seem to know what Gargoyles were.
Why does Nokkar ask Elisa if she knows the truth about gargoyles? He already acknowledged he gave her amnesia – how does he think she can coherently testify to anything?
Goliath: I cannot believe you pulled the trigger on me.
Elisa: Yeah? Well, I can't believe I was carrying an empty revolver. What kind of cop am I?
Goliath: A very good one.
Elisa: That's some story, all right. Gargoyle clans, mutated brothers, magic spells... you threw in everything but King Arthur and the Holy Grail.
Goliath: Yes, well, we haven't encountered the Holy Grail... yet.
Angela: How many ways can I say it? We mean you no harm! It's no use, Bronx. He doesn't understand a word I say.
Nokkar: On the contrary, I understand your words. I simply do not believe them.
Nokkar: Now you are going to help me capture your leader.
Angela: Not if it costs me my life.
Nokkar: One thing at a time, please.
Nokkar: Tell your space-spawn masters, that Nokkar will never abandon his post!
Both Nokkar and the Space Spawn are introduced in this episode. In a Gargoyles spin-off series set in the future, Nokkar teams up with a group of gargoyles, humans, and robots to help destroy the Space Spawn. It would have been called Gargoyles 2198.
