Halsey sensed his former Master and his Apprentice reaching out to him over their force bonds. Slowly, carefully, he opened part of his mind enough for them to get a glimpse of where he was and the proper direction. He also sent an image of Dooku to warn them.
Then he shut his mind enough they could still feel his life force and so he could feel theirs. But they were not endangered by his connection or Dooku's looks into his mind. Feeling their touches of acknowledgement he turned his attention to the room.
Hearing the small sound, almost a chirp, he looked up at the air vent to see his little friend. "Hello again." She gave a tentative wave. Looking up at her, "Why did you run earlier?"
"Master hates me getting under his feet." Her eyes watched him carefully.
Trying to understand, "The Zabrak is your Master?" She shook her head in a clear no. "Oh, so Count Dooku is your Master."
She nodded, "He gets angry if he finds me out of my assigned area." Her eyes were large, truthful, and very solemn.
Looking up at her, "Do you have any company there?"
Checking everything again, "Only the droids." Then, "My caretaker comes in for ten minutes occasionally, but normally its just droids." Before Halsey could say anything to that she sniffed, "Have to go." Then she disappeared down the vent again leaving him alone.
