-Had knowledge of the nature of last night's case despite the case not being leaked to the general public (I think)
The way the victim described it, it sounded as if she'd gone public. She was talking about support groups and charities... things that would make it onto the local news. And she talked about all the attention she was receiving. Even the way Quentin told Christian and Sean... it sounded like he was repeating a news story.
There are a lot of pointers to Liz. She has access to the drugs. You could say she used faulty anesthetic on purpose to torture the fake Carver victim. Then that mixture disappears down the drain. But it just seems SO out of character. The only violent thing her character has ever done (that I can recall) was abort her baby. But that wasn't malicious or sadistic. In general she's a pacifist far-left liberal. That usually doesn't translate into psycho-killer. And there's no way that's her in the Carver outfit in any of the shots so far. Like I said - they could fudge it. But I tend to think they're a little more honest.
