Okay, no free tag only invoke. Clear enough.
Beat grapple block before feed+incite. Clear enough.
WCV might be able to invoke it... but i really don't see any useful way to do it. It's an aspect denoting a disadvantage towards TS...
Invoking aspect to justify "touch" context, thus getting an additional +2 bonus on Incite Emotion.
Towards the last question: No! Two aggressive actions as part of one exchange are out of the question. First the one, then the other.
Originaly i too think "No", but:
1) in Emotional Vampire stated Feed on Emotion and Incite Emotion can be combined in one action
2) In Incite Emotion stated "can be used as maneuver or block".
And this 2 confuses my mind. And if we remember books block+feeding in one time clearly in story.
