The guitarist depicted on Lois' Whitesnake shirt is Doug Aldrich. She claimed that the shirt was her 8th grade concert shirt. Doug Aldrich joined Whitesnake in 2003. Assuming that Lois attended the 8th grade at age 13 - 14 (usual age for that grade), and that the episode is supposed to take place around the time of airing (i.e., in 2011), this places Lois' age at about 21 - 22, at the oldest. Previous episodes, however, have placed Lois as being typically no more than a year older than Clark, which would make her 25 - 26.
After Clark loses his first shield, there are several others lying around the arena, including one leaning against Oliver's cage. Despite that, Oliver ignores that shield and gives Clark a much smaller helmet as a weapon instead.
Oliver: Listen, about this zone, Clark. You know, when you said Jor-El built a prison, I kind of pictured something a little more confined than a national park.
Clark: He built this place so Krypton's worst criminals could have some kind of life.
Oliver: Sounds like a real sweetheart.
Clark: Hey, Lois. Where can I put this box?
Lois: Well, I don't think that requires any super-sleuthing. It does say "living room."
Clark: No, I can decipher your scrawl. I'm just thinking it was mislabeled.
Lois: If you're talking about my Whitesnake throw pillow, loving everything about me includes the sentimental. I made this for my 8th grade concert t-shirt. And I talked to Oliver, and he told me how smoothly he and Chloe fused their hero green and geek chic.
Clark: Don't worry. My "for better or worse" will include your love of hair metal.
Lois: Part of us merging our lives together is taking the time to find the right spot for everything.
Clark: All I know is my perfect spot is here with you.
Clark: We have nothing in common.
Zod: We're from the same world. Do you really think that having powers is the only thing that makes you Kryptonian? it's not. We share the same instincts. We're decisive, single-minded, headstrong. No, we were meant to be leaders.
Clark: Leaders? You're a tyrant who only believes in himself.
Zod: Who else should I put my faith in?
Tess: Lois, I don't want to give up on Clark either. I don't, but we have a responsibility. To not put the world at risk for selfish reasons, which is what you're doing by wanting to see him again.
Lois: I will not let you sacrifice him.
Tess: Being with a hero means accepting that hero's sacrifices.
Lois: That's where you're wrong. Being a hero's wife means never accepting defeat.
Oliver: I know exactly what you're doing.
Zod: Yeah. But you know it's true, don't you? And it goes way back. After your parents were murdered, that anger, that desire for revenge, ah, you can feel it now, can't you? That darkness bubbling under the surface. Terrifies you.
Lois: I wish you could've had a little faith in me, too.
Clark: Lois, I didn't want you to have to make that kind of choice. I was trying to...
Lois: Protect me? I know. But you're part of me now, Clark. Half of a whole. So in the future, if there's even a chance that the mission might claim my better half, sign me up. Because I'd rather be in some sand-blown purgatory then in the hell of not knowing I'll ever see you again.

Oliver: We had a better chance of surviving your dad's desert than Zod's Thunderdome.
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.
Oliver: If you release your pet monkey here, I'd be more than willing to give the Wicked Witch a personal demonstration.
Referencing primarily the 1939 movie The Wizard of Oz, based on the novels by L. Frank Baum. Margaret Hamilton plays the Wicked Witch of the West, the main villainess of the movie. The flying monkeys are her personal servants.
