Annabeth didn't say anything after having her question answered; mostly simply eating her stew in silence. She considered the possibilities - they were kidnapped, yes, but were their bodies converted into data? Or was data some sort of allegory here? Was there some sort of conversion process that she had suffered? If so, was it reversible? Hopefully, but the very idea that she was able to enter and that there is a purported "exit" that should be the case. 

However, she had many more pressing questions needing to be answered. 

"...I'm Annabeth." She introduced herself to the rest of the group as she set down the stew, picking up her digivice and examining it again.
