One of the Phantom Zone escapees is up to no good in the local forest. Clark is jealous of Chloe's new boyfriend from the paper. Meanwhile, Lana and Lex finally sleep together and Lois falls in love with Oliver Queen, Martha's benefactor.

When Tess inadvertently activates the mysterious Kryptonian Knowledge crystal found in the Artic, it emits a high-band beacon which summons an alien queen, named Maxima, who arrives on Earth and begins a search for her new mate, with a kiss that is too strong for humans to survive. Meanwhile, after just moving in together, Jimmy finds a letter that Chloe wrote for Clark that revives Jimmy's insecurities.

After Jimmy and Chloe disappear from sight for a bit and it turns out it has been against their will, Lois and Clark pose as a couple to flush out the kidnapper.

A serial killer is on the loose in Metropolis, and Clark always seems to be one step behind him, while Chloe's paramedic friend seems to think he blacks out and performs the dirty deeds, himself.

Chloe mysteriously returns to Smallville where she gives Clark the idea of killing Davis by telling him he can't keep the beast under control. Unknown to Clark, Tess has gotten together a kill-team affected by meteor rocks to track down Davis so Clark can kill him, but things get out of control when Tess' team discovers that she betrayed them. Meanwhile, Oliver, as the Green Arrow, agrees to help Clark look for things that can stop Davis by breaking into Tess' safe at the mansion to steal some black Kryptonite hoping to separate the two entities apart, while Chloe is revealed not who she appears to be, and Tess is working for another greater power beyond everyone else.
