Smallville, Episode 1.17: Chloe, Clark, and PeteChloe evidently found out that one of the citizens that Clark had helped volunteer for [continuity note from Hourglass] had died and left him a note. Chloe notes the official story (a fire) though it is more than obvious she believes the unofficial one -- spontaneous human combustion. Clark notes her enthusiasm to which she quips - "I'm not happy, I'm intrigued." Pete and Clark both note her enthusiasm as a sign that Chloe's still going to look into it.
Don't look at me. He does that all the time.
Late that day, she finds an article in the Daily Planet about a missing body (which is, of course, ash due to the FotW). Clark notes the similarities and Chloe tells him that "It sure would be nice to check out that house for ourselves." Clark nods in agreement.
