Prue was very suspicious, she wasn't about to let her and Damien walk into a trap. The little bit of bravado she heard didn't exactly sway Prue to believing Alexander's story. At least until he mentioned the thing about her mother. Even now, it was still a sore subject for her, perhaps even moreso than it was back home considering she knew what fate awaited her if she ever returned to her world. Her eyes widened as she felt her chest tighten a bit, the memory of her mother's lifeless body being put into a body bag. How could this boy know that? Was he telling the truth? Was he really her future son? And did she really have a future daughter? Or he could be psychic and was just using things against both her and Damien.
At least until he mentioned the 666 mark Damien had. All right, Prue could count on one hand how many people here knew that. But she was far more inclined to believe he was telling the truth now. But she wasn't letting her guard down just yet. She glanced over at Damien. "I have to say, he does know things only you and I really know. What do you think? Should we believe him?" While she was past the point of throwing the boy through the wall, she wasn't going to let her guard down until she found this wasn't a trap. Did she want to believe he was her son and her daughter was waiting for them in Lawrence? Of course she did. Knowing that she had future children with Damien was very reassuring to her. It told her that she had a future here, that she was happy, and that she lived here. Right now she wasn't caring if the future was a good one or a bad one, all that mattered is that she apparently would get to have the life here that she would never have in her own world.
