Annie gave him a smile at his question, repeating simply, "Safe. Safe place. Safe house." Then she calmly stood up and, reaching into her pocket, pulled out one of the business cards for Angel Investigations that Cordelia had asked her to start carrying quite some time ago. Not that Annie understood the reason (which was primarily a way for someone to return her to the hotel should she ever wander away), but having one now came in handy as she offered Sam one.
The card proclaimed 'Angel Investigations: We help the helpless!', complete with the address, telephone number, and general email information. Anything someone might need to get in touch with those who resided within the Hyperion hotel.
"G-Good... people," she explained patiently, willing him to understand what she was trying to say but was incapable of simply stating. If he needed help, or wanted answers, these were the people to ask.
