Well, it's hard to say for sure. You'd need to look at the creator's inspiration or any background information provided. Maybe it's a completely fictional creation, or there could be elements of truth mixed in.
As I don't know the specific Sally Williams story, I can't say for sure. But generally, key elements in a person's story could include their goals, challenges they faced, and how they overcame those challenges.
I'm not sure which specific 'real life Sally Williams story' you are referring to. There could be many people named Sally Williams. Can you give some more details like her field of work, where she is from or any particular events associated with her?
Sally could be curious. She might ask Percy a lot of questions about the tattoo, like when he got it, why he got it, and if it has any special significance. She could also be a bit worried if the tattoo is associated with something dangerous or unknown.
Another reaction could be that Percy is worried about Sally getting into trouble because of him. He might try to convince her to stay out of it, fearing that the abuser or those associated with the abuser could harm Sally. But at the same time, deep down, he wants her support and protection.
Percy would be extremely hurt. Sally is his mother, and her betrayal would shatter his world. He might initially go into denial, not wanting to believe that she could do such a thing.
There could also be a situation where Poseidon's family eventually comes around. Maybe his more open - minded relatives see the love between Poseidon and Sally and decide to support them. They could offer their protection and help during the pregnancy. Sally's family, with time, might also learn to accept the situation and be excited about the prospect of having a half - god grandchild or relative.
