I didn't feel that Hydro emphasized Lois's previous problems with the GA that much. Well I guess the garbled bit about she'd been looking through her old articles, and maybe robbing from the rich for the poor is a good thing after all, does show her previous issues with him. But I didn't get the sense of any dilemma of a break-up on her part, so much as she seemed quite happy to say that his secret's safe with her, and knowing that Oliver as the GA would come to her rescue. I was just suprised that we jumped right from her confiding in Clark, to Clark and Oliver playing the trick on her. Clark wasn't even shown discussing it with Oliver to try and change his mind (especially after his own problems with Lana and distrust, I'd have thought Clark would have been shown to have some issues with Ollie's plan).

Lois merely admired "GA"'s kissing skills. It doesn't mean she's suddenly into him at Oliver's expense

I guess putting it as the GA could teach her boyfriend a thing to do, just uncomfortably reminds me of the future Superman dynamic, and why it really doesn't work for me for Lois to be more into the man with the mask. But itself that scene isn't that objective I admit. It's more the anvilly winks at the future Clois that makes me think urgh
