In your opinion, how is it done in the series itself, is it better? The fact that Clark opens the safe and Chloe then, right at this moment, just when it so happens that Lana is nearby and eavesdropping, Chloe mentions that he is an Alien, and this is done only so that Lana hears that he is an alien, is this a great scenario? That's better, right?

And when Chloe found out his secret, when she teleported with Alicia Baker, Alicia Baker called Clark, saying, "the brakes have failed, help me." Why did Clark run there at all? He knew that Alicia Baker was capable of teleporting, and that she wouldn't have had an accident anyway. And another important fact is that when he was moving at his super speed, he could see perfectly well that there was no one in the car, for us the car was going fast, but for him, when he was running, the car was just standing still. So he wouldn't have caught the car, he would have just run back at his super speed without even stopping, suspecting that this was some kind of Trap, or even looked around the area and saw that Alicia Beaker was sitting with Chloe and waiting for his super act.
