Archive footage from the series premiere, "Knight of the Phoenix," is used for Michael's flashback to his shooting by Tanya Walker.
Michael is wearing a gray sport coat while in the FLAG semi, but when he backs out with KITT, he's suddenly in his typical black leather jacket.
Devon: A grave was robbed last night. It was Michael Long's.
Michael: Okay, pal, you keep me posted on anything that happens outside, huh?
KITT: Bon voyage.
Mighty Mouth: Arrividerche! Sayonara! Adios! Aloha! Ta-ta!
KITT: Oh, shut up!
Cameron: We can't begin to comprehend [KITT]'s capabilities. I mean, to have it, and Michael Long's death in the bargain, I'd sacrifice anything.
Michael: I'll be right back.
KITT: I'll be right here.
Devon: What has a teddy bear to do with the Foundation?
Mighty Mouth: Anything it can, buster!
KITT: Babysitting a pin cushion... how demeaning.
Gina: Michael, I have this strange idiosyncrasy—I like living.
Gina: What happened? Don't tell me I fainted.
Michael: You fainted.
Gina: I asked you not to tell me that.
