Well, I'm at a big, big disadvantage here. I'm going by a picture; you know the person.

But I have known INFps who appear "emotionally sharp" and intellectually sharp as well....that sharpness apparently coming from strong Fe...although it may appear "introverted" depending on whether one defines things based on Socionics (expressive F being Fe) or MBTI (natural, unforced F directed inward being Fi).

I've known a number of ISFjs, and they never appear emotionally sharp; rather, their emotions tend to be more hidden. That's just my experience.
