Just before Clark falls, Zod stabs him on the right side of his stomach, as he falls the knife is seen on the center of his stomach.
If you pause right before Tess throws her first punch at Zod in the Fortress, you can clearly see that there is already blood on Zod's left cheek.
Right after Zod throws Lois toward the phone booth, his hands go down. In the very next shot of him, his hands are back up.
When Zod throws Lois at the phone booth, and Clark saves her, the window is completely shattered out of its frame as Clark takes her in his arm. However, when he lays her down, the same pane is only partly shattered with a jagged hole in the middle.
When Clark awakes in the barn, he opens the box left for him by Martha Kent. Clark sees the "S" emblem. However when the camera zooms in to Clark's eye to reveal the reflection, the symbol isn't backwards as a reflection should be.
Clark: The Book of Rao is not a Bible. It was created by Jor-El to send the Kandorians to another world, a world they could call their own.
Chloe: Well, let's fire up this intergalactic subway token and send our visitors on a fast train to Nirvana.
Chloe: You know, even though Watchtower's back in the game, I'm still coming up empty-handed on the Kandorian front. It's like they vanished into thin air.
Oliver: You know, that might have something to do with the fact that they can fly.
Chloe: Sarcasm noted.
Clark: Are you saying it's selfish for me to try to save people?
Chloe: You think I want you to go? Clark, I can't imagine being in this world without you. Look, you've inspired an entire team of heroes who will be here to protect us. And maybe your true purpose is to lead your own people.
Zod: How did you get here?
Tess: I flew.
Zod: Icarus flew to where he didn't belong. And he fell to his death from the heavens.
Tess: Icarus was on an ego trip. But I have a higher calling.
Clark: You want war, but it doesn't have to be like this.
Zod: Have you taken a look around you?!? It's always like this! Might makes right! Only the strong survive! Have you learned nothing from the natural world in which you love so much?
Clark: What I've learned is that no matter how much someone has hurt you or betrayed you or how much it seems that someone is evil, at their core, everyone is worth saving.
Hawkman: I've been around long enough to know the best way to win a war is to strike first.
Oliver: No, that's the best way to win a bowling tournament, Tweety. We're dealing with superpowered soldiers here.
Hawkman: Just as expected, Mr. Green Jeans has gone yellow.
Clark: This is the only peaceful way to eliminate the threat. Without a war, a war that no one will win... once the Kandorians are gone, there will be other threats to mankind. The world will need you. You'll have to work together to become the team that you were meant to be. I once believed that my destiny was here on Earth, but now you need to accept that destiny for me.
Black Canary: Clark's right.
Cyborg: We'll protect the world... as one.
Clark: It's been my honor to serve alongside each and everyone of you.
Hawkman: The honor was ours, Kal-El.
Chloe: Do me a favor, okay? Just keep a low profile.
Oliver: I'm wearing green leather, so I'll do my best.
Zod: My only regret is that I can see your heartbreak.
Lois: It's not broken. It's shattered.
Zod: I should've known better than to deceive the Blur's most devoted follower.
Lois: Just who the hell are you?
Zod: Unlike the Blur, I'm someone who doesn't care whether you live or die.
Zod: Unlike you, I will lead from a throne, not from the shadows. Every human, including the woman you love, will kneel before Zod!
Clark: You already destroyed my first home. I won't let you take this one.

This episode marks the last appearance of Allison Mack as a series regular, leaving Tom Welling as the only original cast member left on the show.
Injoke: Although Chloe refers to Green Arrow as "Mole Man" in the singular, alluding to the Marvel supervillain, this also refers to Superman vs. the Mole Men (1951), which featured short bald radioactive mutants from beneath the Earth's surface.
The advance preview includes several clips not seen in the episodes, including a scene from the Fortress where Tess, burned by Zod's attack, is crawling and reaching out toward the camera.
Michael Shanks, Alaina Kalanj, Brittney Irvin, Lee Thompson Young, and Phil Morris appear but are uncredited.
Chloe: Zod doesn't want to play Thunderdome on a planet that is desolate.
Referencing the 1985 movie Mad Max Beyond Thunderdome, the third in a trilogy of movies featuring Mel Gibson as "Max," a former policeman who wanders a post-apocalyptic wasteland. The Thunderdome is a huge gladiatorial cage-dome where parties in a disagreement fight to the death while suspended from bungee cords.
Chloe: I have a feeling the War of the Worlds is coming soon to a planet near us.
Given the "coming soon," referencing the 1953 film and subsequent remakes based on the 1898 novel by H.G. Wells. The movie transfers the 19th century setting of Wells' novel to the 1950s and moves it to the U.S. The basic plot remains the same: Martians seek to colonize Earth and wipe out all of the humans upon it.
Chloe: Okay, Mole Man, just think happy thoughts and keep on tunneling.
Referencing the Marvel supervillain, the Mole Man, who first appeared in Fantastic Four #1 (Nov. 1961), and created by Stan Lee and Jack Kirby. A homely dwarfish nuclear engineer, Harvey Rupert Elder, stumbled across an underground civilization of Moloids. All but blinded in an accident, he swore vengeance on the society that scorned him and launched repeated attacks on the surface world. Over the years he has mellowed somewhat and typically only attacks when he believes his subterranean realm is threatened.
Oliver: No, that's the best way to win a bowling tournament, Tweety.
Referencing Tweety Pie, the small animated yellow canary created by Warner Brothers in 1942. Tweety is the nemesis of Sylvester, a black cat, and belongs to Granny. The character has starred in numerous animated shorts as a Looney Tunes/Merrie Melodies character, had his own series (The Sylvester and Tweenty Mysteries), and has made cameo appearances in numerous other Warner cartoons and movies.
Hawkman: Just as expected, Mr. Green Jeans has gone yellow.
References one of the primary characters in the childrens TV series Captain Kangaroo. Named for the clothing he wore in his earlier appearances, he worked as a handyman and animal handler at the Treasure House.
Zod: Better to rule in Hell then serve in Heaven.
Referencing Milton's epic poem, Paradise Lost, which relates the Fall of Man. The first major arc describes Satan's organization of Hell. He rebelled against God for the reason stated: he preferred rulership rather than bow his knee to God.
