Since Baron Blade is the one who needs to do the incap, heroes incapping eachother would not give Baron Blade the Scenario Bonus. But remember, The Wraith still rolls her defense and it is entirely possible she would block of Bunker's attack dice.

Does that mean blocking optimally is required? The rules (page 9) say "The defender *may* assign each defense die to block an attack die..." I interpret this as explicitly giving the defender a choice of whether to block or not. As in the case mentioned above, it can be strategically sound to not block, on occasion.
I have a followup question though - since the scenario does specify that Blade has to the incapping in order to reap the bonus, does that mean Blade himself needs to do it, or will I get a bonus if my turret does the incapping?
If it is the 3rd Scenario that you are talking about, I counted each incap by a turret or otherwise as part of Blade's incap due to he has to put them out for them to even work. The only one I might be iffy on would be the batallion members.
