Not repeating history or falling for the same tricks as before was a promise Penny had made to herself. She didn't desire to love or to be loved. That wasn't part of the plan. What Penny had now — the relationships she had built with trust and love — was never in the plan, but they happened because she opened her heart.
Hence, another promise was born when she realized these people planned to stay in her life for good. These relationships and these people wouldn't be the reasons she would fall.
That was why, even when Penny was silent, it didn't mean she wasn't aware. She knew what was happening — not everything, probably — but she wasn't as clueless as she had been in her previous life.
Another deep sigh escaped her as she rocked her head before turning back toward the open court. Just as Penny turned, she stopped, catching sight of Slater standing not far from her.
