Aras and Teoman's dynamic in "Daha 17" – How long until the secret is revealed?

After watching all 17 episodes of Daha 17**, one of the most compelling storylines for me is the evolving dynamic between Aras and Teoman.**
Aras finally found his long-lost brother, only to realize that it’s actually Teoman—his current rival. Before knowing the truth, both were constantly at each other's throats and engaged in non-stop conflict. Now that Aras knows Teoman is his brother, his entire attitude has softened, and he has started treating him with care and patience.
However, because Teoman is completely unaware of the truth, he is confused by Aras's sudden change of behavior and continues to act hostile toward him. This dramatic irony adds a great layer of tension to the show.
My question for you guys: How many episodes do you think it will take before Teoman finally discovers that Aras is actually his brother? How do you expect him to react when he finds out?
