Fifth Brother w/ Mag-Pulse Warheads

[BlastDuke]

The Mag-Pulse-Warheads card ability reads:

Quote

Attack (Action: Lock): Spend 1 Charge. If this attack hits, the defender suffers 1 Critical Hit damage and gains 1 deplete and 1 jam token. Then cancel all Hit / Critical Hit results.

How does this work in conjunction with Fifth Brother's brothers ability to add 1 Critical Hit damage after the attack hits?

option a) The Mag-Pulse card text ist executed as a whole and non-divisible, therefore 1 Critical Hit damage from the warhead is applied and then all Hit / Critical Hit results are cancelled (including the 1 Critical Hit damage added by Fifth Brother's ability) => 1 Critical damage + jam + deplete

OR

option b) The 1 Critical Hit damage added by Fifth Brother's ability is added to the 1 Critical Hit damage from the warhead and immediately applied. Then cancel all Hit / Critical Hit results (but there are none left to cancel) => 2 Critial damage + jam + deplete

Thanks for clarification!

 

 

This question is very similar to the "Fifth Brother w/ Homing Missiles" topic

If Fifth Brother (TIE v1) attacks with Mag-Pulse Warheads, and the attack hits, resolve the Mag-Pulse effects as soon as this is determined (during Step 4: Neutralize Results).  This includes the canceling of results portion of the ability.  After the Neutralize Results step, you may resolve Fifth Brother's ability, which adds a critical hit.  The defender suffers this critical hit during the Deal Damage step.
