Smallville

When Sean goes into Jenna's bathroom while she is taking a shower, he is in desperate need of heat, yet the candles stay lit. It isn't until after he kills Jenna, and restores himself, that the candles freeze as he exits.

Right after Sean gets the football on the frozen lake, there is an aerial shot of him walking back to the shore as the ice starts cracking, and the frozen lake is covered with snow. In the next shot, when Sean falls through the ice, he is shown under the clear surface of the ice, as if there were no snow on it at all, or had been swept clear for the shot of his face under the ice.

Right after Shawn breaks out of the lake, he moves to the fire. We see in the first shot that his hands are right close to the fire. However, in the next shot, Shawn is bending down to get his hands close to the fire.

In the begining of the show, they're all at Crater Lake having a good time. The lake is completely frozen over, enough for someone Sean's size to walk around on. At the end of the episode, Clark sends Sean through the air and he lands in a pond in Lex's back yard...that doesn't even have the beginning stages of ice. Unless they had a heat wave strong enough to completely thaw the pond, there should be at least a little ice on Lex's pond.

When Lex says to Clark, "You're like the brother I never had" this isn't true, in later shows we find out that Lex did have a brother but was killed as a baby and that Lex also had a half brother but isn't mentioned much after they meet once.

When Shawn is kissing the girl (right after she comes out of the shower), she gasps when he is kissing her, right before her body turns into a solid block of ice. How could she gasp if her mouth wasn't open? Even if it were just a little bit open, the sound of the gasp would still be different.

When Sean freezes Jenna in her bathroom, you can clearly see that as he lets her fall backwards, she is quite pliable where his hands were holding her shoulders, so she couldn't have been frozen enough to shatter. Contrary to popular belief, a person who is frozen won't shatter when dropped. This can be easily verified by dropping a piece of frozen steak. The skin might crack because it is less pliant than before, but the muscle and bone tissues won't become glass(or ice)-like. Also, freezing a metal lock won't make it breakable by a human either. Freezing things makes them more rigid and less pliant--which won't affect metal much because it is already rigid and non-pliant. This can be verified by the Apollo moon modules which had to endure the freezing cold of space and then land on the moon safely.

In the final battle between Clark and Sean, Sean is in "frozen mode" but there is no blue makeup on the side of his neck in a couple of shots.

When Clark instantly figures out the family bills (see Quotes), the implication is that he has some kind of super-calculating mental ability - this has never been referred to before or since.

So...what happens to Sean? Is he still frozen in the middle of the lake near the Luthor mansion, or did the police or someone eventually show up, chip him out, and haul him off to the Asylum for Kryptomutants? (We find out in the Smallville comic and the Chloe Chronicles Volume 2 that Sean is in a government research center but is bearly alive and has a little bit of a heart beat. How official this is, isn't clear.)

When Whitney is driving Lana home, and they swerve to avoid Sean in the middle of the road, the dubbing of Lana saying "Whitney-look out!" doesn't match up with her lip movement.
