I'm not seeing anything resembling "heavy spoilers" in this write-up. It sounds like the evasive descriptions of episodes that my cable guide writes, with lots of generalities. Even if they HAD provided some concrete plot outlines beyond what any viewer could
assume will be happening, they undercut their credibility when they get a rather important plot point wrong:
Dominique is not Blake's stepsister, she is in fact his half-sister.
Nowhere does it say Cristal and Michael are dead, BTW--just because they're not mentioned doesn't mean they won't be involved with season two.
Edited to add: In my travels elsewhere on the web, I found the exact same write-up from the linked article above on another site...which leads me to believe it's a press release from the CW itself, being reprinted as if its original content on the site. That makes the Dominique slip even more cringe-worthy, but at least it now has a potential author to attach.
