OK, I rewatched the trailer in JP with Audrey's subtitles this time, as well as the FR version! It does give a freaking different impression and it's incredibly more explanatory. They are also giving a clear outline about what's important in FFVII: the future of the Planet, Sephiroth's intent, and Cloud's identity troubles.
At the start, clearly the description is about Sephiroth, and his reason for attacking Nibelheim, as well as worrying about the future of the Planet. What's "amusing" to me is that "Sadness and anger are what makes us strong." can also apply to Cloud as it's what drove him when he attacked and killed Sephiroth. It was literally how he killed Sephiroth, but the second part "but it will change us" is also a clear reference to Sephiroth. It made me go "is this why Sephiroth is trying to manipulate Cloud, to make him change?" If we think about it, it's the reason why he killed Aerith.
The Nibelheim area looks absolutely gorgeous!
Cloud and Tifa's lines in FR are very interesting:
Cloud: T'étais étendue sur le sol. // You were lying on the floor.
Cloud: Alors j'ai pensé que c'était trop tard. // So I thought it was too late.
Tifa: Tu veux dire que... tu crois que je suis morte ? Que je suis pas la même Tifa qu'à l'époque c'est ça ? // You mean that... you believe that I am dead? That I am not the same Tifa than back then, do you?
Tifa's lines clearly replace the OG's "..." to Cloud's comment. What's interesting to me is that Cloud, at this moment, is not sure that he is Cloud of Nibelheim, he does wonder that about himself. I am sure that he reassures her tho because we do know that it's Tifa's faith in him that makes him able to go on with his masquerade. We must not forget that this moment is very important, as Tifa hears his side of the story for the first time and doubts because... he does know things he shouldn't! So, does SHE herself remember clearly? She's been nearly killed and passed away for a long time after all. I feel that SE is trying to make us understand Tifa's own doubts at this moment, about what she knows, what Cloud knows, it's all messy. It's also something fans have been harping on about her for long, so I am 100% certain that they want to clear up this.
In French "what facts are only fiction?" is kind of hitting hard :') We see Aerith praying for Holy and Holy in the water juuuuuuuuuust before that line, a bigger hint of what's to come. The final flashback in front of Midgar... What Cloud says isn't correlated with this flashback I think. We see Zack and Cloud in front of Midgar but... I think this might be a scene from Zack's side, from before he arrived in the church in Intergrade. The outskirts don't look like the Last Stand's one, but from a little after the crew passed them at the very end of Remake. So I think we're seeing Zack's side there.
Cloud could be an added or changed dream (like the one he has in Junon), or it could be a memory triggered in the mansion when they find stuff about their capture. It's kind of easy to add. It could be Nibelheim, but it could also be a new location (from an OG perspective) when they met elsewhere in CC - I don't remember the name sorry. It is however most probably in Nibelheim. The fact that Cloud remembers Zack when Jenova specifically prevented him to even hear that name when Aerith asked him about Zack is very interesting. It makes me think that it's a dream because it's the only way for the real Cloud to plug in, so to speak, but even then we've seen Jenova manipulate his dream with his mother. So I wonder what is the justification of this all and how we're going to get this - clearly this time around Zack has the proper weight in FFVII's story.
Clearly too Aerith's iconic line is from the GS date - it's very ballsy of SE to use that line for a Zerith feel lol. It also means that the GS dates will still be there - and as I stated before we'll have more clerith on the way too, because just like in the OG, Aerith needs to fall for Cloud. As for Zack's line "sorry, I don't know how to help you" feels like what he's telling CLOUD at this moment, in front of Midgar. Because he realises Cloud is too far gone and he can't help him at all. He probably felt helpless, not able to help his friend. I think this is why he was alone in front of the church, because he probably left him to someone in the hope they'd be able to help him.
In short: we're being given FFVII as promised. With just a pinch of Zack!
FR version for those who can speak and read French:
