“The last bit of sand in the hourglass was almost through” … while this is a lovely metaphor, I don't feel like the scene needs it. Like it's cluttering up the paragraph I guess?

“her amber eyes bore[d] into the door willing it to open” … bore feels odd to me, I believe you want bored even if it looks weird

“Seventeen was too early for a girl such as her to give birth, especially alone” … this line reminds the reader that her pregnancy is weird on multiple levels. I had forgotten that she was seventeen but you reminded me and made me think about how old Fabo is.

Wow! That scene with Seiton yelling at Helen is pretty intense. He's sort of an insane nonsensical rambler going from one subject to the next like that, but I could definitely tell he's angry and powerful.

“dragging her to the operating table” … wasn't Helen already on the operating table? I assumed she was because the Med robot was doing holographic scans and was about to perform the delivery. And later you write “When it finally gotten her inside the operating room” so she's not even inside the operating room yet? Oh, and grammatically that would be either “When it had finally gotten her inside the operating room” or “When it finally got her inside the operating room”

“a firefighter carrying a child out of a burning” … this language is making Helen a child again, which bothered me the first time you did it back when they first met. I would go with something like “a firefighter carrying a woman” and avoid the child language.

“Fabocusa said as he put a gas mask on her” … how is Fabo carrying her in both arms and also putting a gas mask on her face?

“The roads opened up with erupting flames, which spread like wild fires[. People were] getting burned alive” … otherwise this line can be read as saying something like “the flames spread like people getting burned alive” which doesn't make sense.

“the heat and gas had eaten the dye off of Helen” … ow ow ow! So she's got liquid hot dye running off her skin? Or did her sweat make it come off?

“If I go with you, Seiton will gain control over the portal” … actually it seems like Seiton can pretty much control anything anywhere even if someone is there, I don't even know why Seiton would let the portal work at all … unless he doesn't have access to it but then Fabo should be able to go through

“Tears ran down both of their cheeks. She nodded” … hmm, I think I feel like his heroic sacrifice and her acceptance of it should be a bit more difficult? I mean I know that time is an issue but … it feels like she suddenly accepted it because she had to for the plot, not because she actually was able to accept it. Maybe if she hadn't just said she would die with him I would believe that his telling her to live for their child persuaded her.

“He smiled [as a] Spacer ship crashed”

Another excellent chapter from you. Lots of action, lots of drama … Seiton was a little awkward with his rambling but trying to kill Helen with her med robot was a nice touch. I was a little surprised when Fabo announced he had that really convenient portal escape but then I remembered chapter 0 and how they sent all the Titans away with a giant convenient portal … still, it feels a little too convenient. And how has Helen not given birth yet? Willpower? The baby was just about to come out but then Fabo carried her across the city on foot?

Any questions?
