When Clark catches Lois as Stiletto, she says "weren't you supposed to feed Shelby, is there no woman you haven't stood up?" The dog is male.
In the last scene between Chloe and Clark, Allison Mack mispronounces the word "silicon," pronouncing it "sil-i-KONE" rather than "sil-i-KAHN." There are no such thing as silicone microchips.
Clark tells Chloe that he grabbed her laptop before the police arrived at the Ace of Clubs. However this room was filled with kryptonite which stopped him in his tracks when he first went in to the room.
Lois: I'll get my best men on it... and when I say men, I mean me because I work in the basement.
Lois: Okay, obviously there's been some sort of mistake. It's not like I squeezed into 5" booted heels for my health.
Hostess: Miss Lane, there's simply nothing I can do.
Lois: Actually, there is. You can tell Edward R. Murrow that he can kiss this cub reporter's sweet...
Lois: You're only as good as your last story, and I wrote mine so long ago it was practically with a feather pen.
Lois: Meet Stiletto. I was going to sew an "S" into the chest. Is that tacky?
Lois: (with British accent) Lois? Who's Lois? I'm Stiletto. I should get back to my cave.
Clark: Lois, you could have a bag over your head and I'd still know it's you.
"Blur-etto" is a reference to the Clois fan-made word that represents Clark and Lois pairing in stories.
