From there, it's either Fi: attraction/repulsion and building interpersonal relationships or Ti: comparability of objects based on objective qualities (like metaphors), but neither H.A. slips out as easily as it will if they were somebody's dominant function.
That's my take on it, and really I just typed him based on my knowledge of the system so hopefully it was clear what I was trying to say and possibly food for thought.
