Incite Emotion (with Lasting Emotion) allows you to use Emotion-touch to perform a maneuver at +2, a block, or a weapon:2 mental attack.  Emotional Vampire allows you to feed on a target, inciting mental stress, and gives you a +1 bonus if you feed on the same target for more than one round.  They rules say that you can both Incite Emotion and feed off of that emotion with one roll in a single exchange. 

Now for the questions.

A White Court Vamp with a Deceit of +5 and lasting emotion uses emotion-touch on a target.  He decides to go with a maneuver.  His target has a discipline of 3.  Assuming they both make a 0 on the roll, the maneuver will have 4 shifts of strength, placing the aspect "greedy" on the target.  At the same time, the WCV decides to follow through with the maneuver and feed, based off of the same roll.  How much stress would he deal?

I can see several possibilities:

4 stress: The attack uses the exact same value that the maneuver did. This can be broken down in to whether or not the victim gets a second defense roll against the attack itself.
2 stress: The attack uses the same roll, but doesn't get the +2 bonus that the maneuver grants.
1 stress: The target defends the 4 extra shifts as though they were a separate attack, and once again rolls a zero.
6 stress: As per the 4 stress option above, but the mental attack hits as a weapon:2 because the WCV has Lasting Emotion.
4 stress: As per the 2 stress option above, but the mental attack hits as a weapon:2 because the WCV has Lasting Emotion.

Which of these do you think would be the result?
