Why does Thea Queen in Arrow hate Malcolm Merlyn now?

In Arrow season 3, she started to love her father & accept him for who he is, weather he's a killer or not. But yet, in episode 13 she seems to all of a sudden hate him. I don't get why? Why has she all of a sudden gone against him? I know he's evil, but what changed her feeling about him exactly? I know she found out that Merlyn didn't tel her Oliver's secrete when he knew it, but why would he tell her? It wasn't his secrete to tell, so why does she hate him now?

Because she realized he manipulated her, although she doesn't know the full extent of said manipulation yet.

And why do you keep making threads like this? You know we have an Arrow thread here to talk about the show right?

Because she is a self-righteous brat, always has been.

But what reason would he have for telling her Olver's secrete? Even if he hadn't manipulated her, he certainly shouldn't be telling her Oliver's secrete, because it's not Malcolm's secrete to tell. Oliver would kill him (figuratively) if Malcolm told Thea his secrete.

Oh right... Is that how the TV forum works? Every question has to be under the set thread?

^ makes more sense than creating a new thread for each inquiry.

That bugged me too

because it is written in the script...
