I know that Genya and David had to leave and be terrified of the Darkling, because they were on Alina's side in the books (like, I still don't really get why they turned on him beyond "Nichevoya icky" which still doesn't make sense. Like, I guess "something, something, Alina's forgiveness", but that's even more dumb so I'm choosing to ignore it). But honestly, I just wish they had stayed.
I wish we had scenes of Genya being one of Sasha's right hands. Maybe have her take over the Healers' wing for the time being, because so few Healers made it out and a mix of Tailoring and Heartrender's first aid powers is the best they're going to get, anyway.
I want Genya to come into the lab, pull Vladim and David away from their desks and remind them to eat, because they've both been In The Zone and forgot to eat since breakfast and it's almost sunset. I want Genya to chat with them over the dinner and let them bounce ideas off of her, because she's an expert in her own right and because she's as much a Fabricator as she is a Corporalnik.
I want Genya to ask Vladim to make some salves for the Healers' wing, if he has time, and commenting on his unusual techniques, because he's self-taught. Maybe giving him some pointers from her own experience.
I want Genya to sit with one of the rescued Grisha, who had been through hell at the hands of their former comrades-in-arms, trying to heal them with her limited abilities, apologizing when it does not work. I want her to hear the stories of noble Healers, who sacrificed themselves so that the others could escape. I want her to ask them, if they want to keep the scars - some do, because scars are a good reminder, some don't, because it pains them to see those same reminders.
I want Sasha to walk through the Healers' wing, offering amplification to Genya and the Heartrenders, so that they might save a life.
I want to see the Loyalists train together, joke together, offer encouragement to a Grisha summoning for the first time after a traumatic injury, or finally walking after being bedridden for weeks.
If Sasha must suffer through Merzost, I want the to look at him with sadness, not fear. This is their leader, their savior, and he's being killed by the very power he needs to save them, save Ravka, save the world.
I want a toast raised for their fallen allies. I want to hear them give goodbye to the fallen the Grisha way. No Saints. Just the inevitability of "They have returned to the Making" "As we all shall".
They have lost so much, and will lose more, but in the end, it's worth it, because it's for the greater good. For the Grisha in Ravka today, tomorrow, for Grisha everywhere.
