I'm so giddy about the way they decided to re-introduce Elena's character in the new trailer because I was worried at the idea they would take the route of doing what the fandom (who don't read the novels) mostly perceive her with: a comic relief due to her klutzy tendencies & her crush, who constantly need to be hand-held by the boys in the group to the point the fandom interpreation render her as a shy or genki girl/ almost swap her personnality with other female characters as if she was a blank state.
But the devs instead decided to follow throught how she was depicted in the compilation: A flawed, fierce, unapologetic woman from the slums coming from an emotionnally distant family, who was the top student of military school while working in a bar in Wall Market prior joining the Turks ( who used to belittle her all the time, mind you) for the sake to gain people's approval, to prove that she's better than her sister and doesn't hesitate to beat up & torture people in front of their sickly relatives. her gung-ho attitude create a mutual frustration in the group, even Tseng doesn't really get an hold on her.
She also can be competent as she was the top student of the military academy but also did some significant contributions post-OG: She is the one who managed to have Midgar's population mostly evacuated post-Meteorfall, she is the one who goes to ask questions to people during investigations, she is the one who maintain a cordial relationship between the towns around Healen's Lodge by proposing & organizing the distribution of medicine to Rufus & then goes looking for the materials & employees necessary for its production. She is the one who find the Jenova's remains in AC & get them to Rude & Reno before going back to fight the remnants to help Tseng. She was in OG the Turks with the most powerful stats as well.
She's not a character you can swap with Cissneï (like some people apparently hoped?) We don't get to skip or not her boss fight this time. She is re-introduced as her class of origin: a martial artist (instead of giving her a gun like in AC). She is an actual threat & even Rude this time warn the party about it. Which I hope will be kind of omnimous story-wise as I think Avalanche & the Turks may become more & more aggressive toward each other throughout the story.
I think we're also gonna see interesting dynamic in the group, as since she's the newbie with an inquisitive & active side, she may be the player eyes into the dynamics & conspiracy in Shinra.
I also think it's the first time we see a Turks get that violent with Aerith & we know that Reno, Rude & Tseng cares about her. Among the group, the one who is never show feeling sorry about being a Turks is Elena.
I hope Rebirth will finally bring justice to her, with her qualities & flaws. She is as important as her comrades within the structure of Shinra & I want it to be explicitly acknowledged in the story.
