Chloe and Clark attend a party out at Crater Lake where Chloe makes the first reference to Lois in the whole series: "Just because I don't have raven hair and the initials L.L. doesn't mean that guys don't find me attractive, Clark." Of course, given Lana's looks in the series, it has a double play to Clark's official love interest on the show as well.
When Clark is not happy about Chloe's choice in possible boyfriends, Pete tries to hook Chloe and Clark up. Clark is right to worry; Sean Kelvin is bad for her and is the first in a line of bad relationships for Chloe in the series. Chloe makes a crack about being a Crash Test Dummy (a reference to their Superman Song, no doubt) for their dating skills and tells both of them to treat her better. The three of them run into Sean later that day where he blows Chloe off because she's putting the paper to bed; she comments how once Clark hooks up with Lana, there is no "luck left for the rest of us."
