It seems like Thea might play a very crucial role in the Slade-Oliver feud in season 2, episode 19 of Arrow, according to new reports.

Oliver and Felicity Join Forces to Take Slade Down in Episode 19?

It seems like Thea is finally unravelling as she seems to have become the target of Slade's attacks to get Oliver's attention. In the last episode she was kidnapped and in the next episode, Man Under the Hood, of the CW sereies, it seems like Slade will be using her as a human shield in Oliver's lair. She also learned that Oliver and her mother had been lying to her about the true identity of her father.

Here's the official synopsis for The Man Under the Hood:
