I don't have a problem with it, precisely for that reason. I'm much more annoyed that Thea apparently STILL doesn't know.
Well fortunately it doesn't seem like that particular problem will persist after this weeks episode.
At least Lana had some relevance in the first two seasons.I honestly would not be surprised if Thea goes int the whole "You lied to me for many years; how can you expect me to trust you after this?" routine once she does learn the truth.
She's one of the most self centered characters on a comic book show that isn't a villain. She makes Lana Lang (at her worst) more easy to watch.lol
