grammaticality - Implied subject with "i.e."

Is it required that an i.e. clause have an explicit subject? Preferred?

E.g., is the following sentence correct?

She was not amenable, i.e., turned him down.

Or would it have to be

She was not amenable, i.e., she turned him down.

I.e., can you use i.e. to clarify only part of a sentence, or must you use the full sentence (and restate the the other part that didn't bear clarifying)?
