E! Online’s Kristin has confirmed that Chloe will not be in the episodes this year. So we can expect her to come back in the episodes next year to wrap up her story.
Michael: Anything about Chloe on Smallville? Enough about Clois! Will Chloe be back at all before 2011?
Per a good source: Chloe will not be back at all in 2010. Sorry!
