@kouch_lee:
She made it clear before that she doesn't like to fight, I can get (and totally understand) that. Not everyone is a fight monger like Zoro or Luffy. But she's been doing it all this time, she only needed one last push. Again, was she afraid of dying? Hell, she could've died a thousand times in the Colosseum before, yet she mustered up enough courage to try and take the Mera Mera by herself and dethrone Dofla on her own! That's actually closer to having a death wish than being afraid to die. And yet, as soon as she sees Diamante, she's so scared and/or tired of all the fighting (SERIOUSLY, NEED HELP WITH THE TRANSLATION IN THERE! HAAAAALP!) she can only run away and cry for her daddy's help? No, sorry, it makes not much sense.
Again, whoever expected Becca to wreck or even manage to stand against Diamante for more than 1 minute was fooling him/herself. But I DID expect her to at least try and slash her mother's killer instead of going "oh shit, the man who killed my mother, he's gonna do the same to me, I'm scared, I'm outta here!". That was honestly disgraceful, independently of her mindset or willingness to fight.
In fact, that was even an act of betrayal towards her fellow countrymen. Fuck, THEY're trying to do something on their own! Yes, something incredibly stupid and foolish (going after Dold's head), but they're trying to act cause they can't stand seeing their friends and family killing themselves right in front of them. Rebecca is at the frontlines, but as soon as her mission of "giving the key to Law and Luffy" finds a stone in her way (Diamante), she runs away? The little girl that tried to save the entire country on her own, now that has plenty of companions to help push her forward and give her strength, now of all times, this little girl crumbles and runs away in an act of sheer cowardice? When even your average Joe armed with a fucking broomstick is trying to help end this nightmare, putting their lives on the line, Rebecca of all people suddenly thinks "oh shit imma get killed I'm out BYE!"??????
No amount of explanations will make this right.
I get why you're upset with her character, I do. I just think you guys are still looking too much into it. Those eyes and the heart pounding in fear didn't really strike me as "get ready for this whoopin' scrub". I pretty much assumed she'd be running and crying while Diamante taunts her. She hasn't been shown to throw a single attack(besides the half-ass Luffy ambush). I feel like she's been in full emotional mode since the colosseum. She finds out who murdered her Mom and has to fight him. Then she remembers she has a father. Just too much for her overall character to handle. Now if from the moment she left King Riku and was al like "Diamante is mine, I've got a score settle" I would of been like wtf too. I do get that all of her countrymen are fighting too. This is just my opinion
You're right on the no amount of explanations though.
