Fortitude vs Additional Stikes

Minion A hits for 1 Damage. Minion B plays Hidden Strength, spending a blood to prevent 2 damage. Minion B plays an additional strike for 1 Damage. Does the Hidden Strength prevent the Damage for both strikes if payed for during the initial strike phase?

Or, in general, can damage prevention affects that exceed the inflicted damage of an opponent's initial strike be used to soak damage for additional strikes in the same round?

Damage prevention does not carry over to other damage resolution phases (e.g. another round) unless explicitly stated otherwise. As every (additional) strike (pair) has its own resolution phase, damage prevention works the same, therefore prevention does not carry over to additional strike phase by default.

So, if I played Unflinching Persistence at Superior to use the optional maneuver, I couldn't use it's "Prevent 1 Damage" affect on any Strikes except the first one that round?

This isn't intuitive to me. If someone bleeds me for one and I reduce it by two and they increase the bleed by one, doesn't the bleed still fail since I reduced it by two? It's a similar sort of situation.

Unflinching Persistence

Combat
Fortitude
[for] Prevent 1 damage.
[FOR] Maneuver, and prevent up to 1 damage later this round. Only usable when choosing range.

Unflinching persistance gives you ability to prevent later in the round (a delayed effect). Additional strikes damage resolution phase is still within the same round, therefore you are eligible to keep the effect for additional strikes.

This is not the same for bleeds, because bleeds (votes, stealth, intercept) can be negative. Therefore if you reduce a bleed of 1 by 2, it goes for -1 and +2 bleed is needed to inflict pool damage.

To be precise, damage gets negative for (only) that phase too if you over-prevent it.

Hidden Strength
Type: Combat
Requires: Fortitude
Cost: X blood
[for] Prevent X+1 damage.
[FOR] As above, with an optional press.

Each round of strikes has it's own strike and damage resolution phase. Unless card text says otherwise, you can only prevent damage that exists in the current damage resolution phase. Extras don't carry over to other combat phases.

A bleed of 1 reduced by 2 equals a bleed of minus 1.

It's a similar sort of situation.

It's different. Striking a second time is analogous to bleeding a second time in a separate action (except that the latter is usually illegal).
