I will stand by my belief that Jack is a civilian, not a fighter. I mean, aside from the fact that he looks shit scared and completely out of his element whenever theres a threat,
(some exceptions notwithstanding) there's also his total lack of fighting technique.
He has maybe 3 moves, total:
- standing in defence (staff raised in front of him, usually tight to his body with both hands gripping it)
2. using momentum or distraction to carry a hit (see how he's gripping the staff towards the base so he can give it a wider swing - generating more momentum which makes the hit harder)
and sparkles attack is a very new thing for him, it's the only reason he has any confidence in a fight, because he thinks he's discovered the atom bomb of attacks.
but it's not actually that effective, it caught Pitch off-guard sure, it revealed Jack's potential, sure, but once Pitch knew what he was up against he countered it easy-peasy.
what the sparkles attack actually does is give Jack a ranged attack, which is where he's most comfortable.
(side note: rotg does have a continuity issue with the sparkles attack. It's supposed to be a new thing, as previously he was limited to using touch to summon frost/ice onto a surface,
even in the sled scene, he's still using touch by dragging his staff on the ground, summoning the ice and then directing it after the fact.
but there's two instances prior to the sparkles being discovered where he uses that ranged ability,
he shouldn't have that ability yet, hence, continuity issue).
so having that ranged attack allowed him a foothold in a fight, but he's still inexperienced, so you end up with those moments in the final fight where he's caught off guard,
and while I'm arguing here that it's because he's a civilian and is not trained to deal with these situations, there's also his overarching development coming into play here.
He's spent the rest of the movie relying on others, dodging responsibility, and the antartica/memory scene really signals a change for him where he accepts that he needs to hold his own weight a little more. Him charging into this fight solo?
to me, that's the warning signs that Jack's taken that lesson too far. He's aware that he needs to hold his own in a fight, but he lacks the experience to understand that he needs to do so in moderation.
but that's a problem for future Jack (and fics) to deal with.
I want to circle back for one last point,
the comfort staff. Jack is constantly holding his staff up like this - close to his body, both hands gripping it. But this isn't a good defensive stance, he's not ready for an attack here.
Jack's attacks have him holding the staff in one hand,
there are some exceptions, but in general, he's attacking one handed. Again, using the momentum of the swing to carry his shots.
A much better defensive stance for Jack would probably be, funnily enough, a more open one. But that's where confidence is needed, and confidence comes with experience, which Jack doesn't have.
Jack behaves like a scared civilian, because he is one as far as I'm concerned lmao.
anyway, I apologise for the tangent, I'll take any excuse to yap about my boy.
