1. For example I'm flying Millennium Falcon with old Fat Han, but instead C-3PO I've Hotshot Co-Pilot. And I'm shooting in someone who have two focus tokens. In first shooting I've missed (he rolled focus and evade, so he MUST spend focus token and he did it and he has no damage) and I'm triggering Gunner. In these case, after Gunner he also MUST use second focus?
2. For example attacker is shooting on me, and I’ve Hotshot Co-Pilot. Attacker has focus token and Target Lock on me. After shooting he has rolled on three dices “blank/blank/blank”. He has to spend focus token now before re-rolling (even if this will not give him anything), or he can re-roll first and after that he MUST spend focus token, even if there still will be only blanks? When is that moment when attacker MUST spend focus token in these case?
