- Clark Kent: I'm glad you were around when I needed you. I'm not used to others doing the rescuing.
- Jonathan Kent: Yeah. Well, that's what parents are for, son.
- Lt. Harris: Sergeant Johnson, the SWAT officer who tore up the, uh, agriculture show, any reason why he'd try to blow you to bits?
- Superboy: I haven't got a clue.
- Lt. Harris: That makes two of us. I can't get any of this to add up. I knew Johnson. He was straight as an arrow. Not a head case. I must be missing something. Something must've happened last night when Johnson and his partner came across the break-in at the cryogenics lab.
- Superboy: Cryogenics lab? There was a break-in?
- Lt. Harris: Yeah.
- Superboy: Do you know what was taken?
- Lt. Harris: Some vials, box of hypos, different things.
- [seeing his reaction]
- Lt. Harris: What is it? What's wrong?
- Superboy: I hope it's not what I think.
- Professor Peterson: Amazing. I mean, there were enough explosives in that van to topple a building. But you seem to check out just fine. I mean, from what I can tell. I mean, even x-rays can't penetrate your skin.
- Superboy: I feel fine, professor. Really, there's nothing to worry about.
- Professor Peterson: You may be feeling no ill effects now, but you did black out.
- Superboy: Yes, I did, for a second or two.
- Professor Peterson: More like a minute. The point is, you're not completely impervious to physical trauma. Now, take this laser. It's powered by green space rocks that emit a radiation harmless to us, but deadly to you. Now, why? I mean, what is the link between you... and an unknown green element? And this morning... you survived the immense heat of a major explosion unscathed. Now, what if it had been the heat of a... a 50-megaton hydrogen bomb? And then there's cold. Could you withstand temperatures approaching absolute zero?
- Superboy: Beats me, professor.
