The curse of the fallen Homie.
Lin, Carlos, Aisha... Now Neenah?
Or it could be another Johnny Gat scenario, where she is assumed to be dead, only to return later in the story?
I can only hope.
Edit:
All I know about these characters is the little footage and info we've been given about them, so it's like: "Meh, sounds cool, whatever". But as soon as someone mentions that one of them could be getting killed in the game, it's like: "Noooo, they're my favorite character!".
Edit:
When I think about it, we know that these Saints are starting from literally nothing in this game, and it seems like their outfits progress along with the main plot (Kinda likehow Purgatory progressed throughout SR2's plot).
And I can only assume that this game is going to take the route that most superhero origin movies do. Which is where the Superhero takes at least 50% of the movie to discover all their powers and decide on a final identity and design, before the main event takes place.
So I imagine the colour purple won't start making an appearance on the main characters' outfits until at least 45-65% of the way through the main plot.
And since we've seen the characters in at least 3 different styles in the various footage we've seen so far, it's safe to assume that Neenah is still alive for at least 45-65% of the plot.
Now if we look at the past Saints.
Lin didn't get killed until the 9th Mission (including Strongholds) out of 13 in the Rollerz Arc.
Aisha got killed in the 7th Mission (including Strongholds) out of 15 in the Ronin Arc.
Carlos got killed in the 6th Mission (including Strongholds) out of 15 in the Brotherhood Arc.
As you can see, the kill seems to happen earlier each time, though the order on which Aisha and Carlos get killed may vary depending on which Arc you play first. Unless you play the arcs alongside each other, then the order still applies.
So Neenah would be dead before the 45-65% mark.
Now for Gat's timeline of "incidents".
SR: 7 out of 16 in VK Arc
SR2: 7 out of 15 in Ronin Arc
SRTT: 2 out of 4 in Saints Prologue
Now forget the numbers, and look at the percentages.
His "incident" happens around 45-50% of the way through his plot.
And if people have already picked up on Neenah's scorpion emblem being associated with "death", and Gat was assumed to be dead during SRTT, only to return in SRIV during the 15th Arc in the game out of 21.
Maybe Neenah is thought to have been killed around 50% of the way through her Arc, only to reappear at the beginning of the final quarter of the game's overall story.
Or maybe I've been awake too long today and need some sleep?
