You'ren looking at the point I'm trying to make. The point is that Sephiroth, for the sake of setting of the stage and putting importance of Sephiroth's/Clouds relationship into context - shouldn't be appearing in the game so soon regardless if it's the same scene or not. Sephiroth doesn't appear until you're a quarter through the game on the Junon Boat.
Because at that time, the stage had been set by the discovery of headless Jenova at Shinra HQ and Sephiroth's sword moments later. Which gave leeway to the importance of Clouds memory when they fill in the rest of the party (and the gamer) why Sephiroth being STILL alive is a big deal - despite Tifa and Cloud believing he had died years earlier.
THAT'S the point I'm trying to make...
Well I mainly wanted to make it clear that we don't know when this scene occurs. It could be after they leave Midgar.
But even if it's not, depending on how extensive the Midgar portion of this game will be, it may even be more appropriate for the pacing of the story to introduce Sephiroth through a flashback while in Midgar, rather than when they arrive in Kalm.
Right... I already clarified that much in the bolded characters. But let me make this SUPER specific so we don't all get hung up on small details.
What I meant to say, is that you don't meet Sephiroth in the flesh (so to speak) until the Junon Boat. I didn't use Kalm as an example because it's a flashback. I'm aware that the teaser trailer is insinuating it's also a flashback, but inserting a flashback at some point in Midgar is shitty writing - and does a piss poor job of setting the stage with Sephiroth as a character/villain.
To be super specific, you don't meet Sephiroth in the flesh in Junon either.
That was one of Jenova's abilities.
I guess your concern is that one of these people show up in Midgar, and confront Cloud?
I don't expect that to be the case. This may just be what Cloud sees when he hears that mysterious voice talking to him in his head, or a flashback.
But again, depending on how long the Midgar section is in this game, it may be more appropriate to introduced things like the Kalm flashback while in Midgar instead.
