Silver couldn't begin to understand how Pan felt in regards to being thrown out, and she was doing all she could to make him feel that he was welcome back. His confirmation of her being right about his intentions on Jed's boat only made her believe he should be welcomed back more. He'd been screwed over, and if Gypsy had been there, she would have made everything clear to Jed or she would have at least kept Pan from leaving. But the reality of the situation was that Gypsy was gone, and that was a loss for both Silver and Pan, and that was definitely something that she understood his feelings over.
The very least she could do in her sister's place was let Pan know that she knew the truth and that it was okay for him to come back. She wasn't and probably would never be as close to him as Gypsy had been, but she could do her best to make things easier. She didn't hold a high-ranking position in the tribe and was only regarded differently because she was Gypsy's sister, but she knew Jed would listen to her.
"I kind of figured she'd be worried," she admitted in reply to Pan's revelations. "I was expecting a lecture of some sort. That's why I thought she'd be ashamed. I mean, I understand how she would see it. Jed, as she knows him, isn't exactly... the most faithful man." She paused, glancing Pan over again as she set her hands on her hips. "Whether or not you choose to believe me about people being worried about you, I want you to know that I, personally, have no problem with you coming back. It's your choice, though."
