Tyler has no plans of hurting her nor locking her up. He just wanted to be with her. That's all. He wanted to ask her if she had a feeling for him. But he wasn't able to get a chance of asking her because his brother came.
He feels guilty about what he did. He shouldn't have done that. But he knows it's too late for regrets. He deceived her by having her take sleeping supplements. He gave her the impression that he's a bad person. Is he really a bad person? He just wanted to feel some love. When he saw how their eyes locked, he knew that she has something for his brother and it hurt him big time.
His heart feels like he wants to keep her beside him and force her to love him. But he's not that bad to do that. It's not that he will force her but at least he could get a chance to be loved.
