REVIEW: The only episode to really focus on Mercy Graves, in Ghost in the Machine, it's quite clear to the viewer (and later, to Lois) that she's in love with Lex Luthor. This mirrors Harley Quinn's story in more than one way as Lex is absolutely wretched to her and treats her like a lap dog. Even she admits that he "made" her, an urchin off the streets trained to be his bodyguard/work-wife. And that has a strong pull on her no matter what he's up to and how he treats her. Unfortunately, we're very far from her getting her due.
The return of Brainiac is merely acceptable however, regaining mobility with 4 minutes to go and getting blown up almost immediately. He's actually more effective and terrifying as a computer program infecting the technology around him. He has cool crab-like drones. He sabotages LexCorp operations (but really, Lex sabotages himself by staging incredibly dangerous presentation and firing missiles at his own board room; he might not NEED Brainiac to ruin him). He sends missiles to Clark Kent's apartment (triggering a cool sequence where Clark catches a sidewinder and then has to deal with damaged bridge pieces collapsing on one another). All without a body. Sure, that's HARDAC's shtick, but what's good for the bat is also good for the gander (so to speak).
Whenever we see Lex and Brainiac team up in the comics, it's never a good thing for Lex. While this isn't a team-up per se - Lex is a hostage - they do need to collaborate. Lex simply rebels too late, and Brainiac proves he's the colder and smarter villain. He needs stronger plots to fulfill that promise though.
REWATCHABILITY: Medium - Of interest mostly for the exploration of Mercy's relationship to Lex, this is otherwise a fairly ordinary affair.
