When Seth asked Lana if he could take her out sometime she said "How about tonight?". This was in the hospital where Seth has a large cut on his forehead. Then the audience sees Clark talking to Martha and Jonathan about how it happened like it was a day or two ago. And when the audience sees Clark talking to Lana at the Talon after that, they're talking like it was a day or two ago. Then Seth rolls up to pick up Lana for their date in the same scene and his cut is almost 100% gone.

When Seth and Clark are walking through the school corridor, you can clearly see someone in the background in the doorway wearing a headset with a mic.
When Chloe accuses Lex of hiring Mason to steal back one of her computers, she says that, compared to Lionel, Lex is "euphemistically" the lesser of two evils. A euphemism is a word or phrase substituted for another in order to sound less offensive or harsh, such as "passed away" for "died"; Chloe more likely meant Lex is metaphorically the lesser of two evils.
