neuro's bomb was supposed to be a reference from "keep talking and nobody explodes". the theme might feel slapped on but id like to share my side, neuro's memory got messed up a bit after evacuation, so when she tries to comeback, she remembers the events that happened on that flashback as a playable mission, what happens on that flashback mission affects your entire composition, if vedal dies in his mission, he's dead unless you go back and restart his level, same goes with every other hero/vtuber ingame, thats why if a hero dies, they cant be used because neuro remembered they did die. so every unit you fail to rescue becomes a remnant of neuros past, unless you go back and change it of course. but i will agree it does feel a little tacked, however i personally think its not that random story wise.
