What ever happened to those lambda scientists? Emma asked for all the cattle children to cross over but nothing was mentioned about the scientists + she also said there should be no crossing over between the worlds. Did the demon god justβ¦idk leave the scientists with the demons in the demon world while the rest crossed over?
All the Lambda scientists are dead by March 2047.
(Chapter 119 | Chapter 129 | S2 Episode 8)
It's implied they were all (conveniently) killed off in the explosion Norman masterminds to keep with Shirai's desire for the cattle children to maintain their innocence/"whiteness" in the neverland, i.e., not have Norman or any of the other Lambda children be forced to murder any humans there in a direct confrontation, only demons.
(Shirai in Mystic Code Book Chapter 4 on plans to have Ray or one of the other children kill Andrew | Exhibition Interview)
Even at the mass production farms only the corpses of demons are shown amongst the combatants, so it feels safe to assume human scientists were only at Lambda 7214 by 2047.

(Chapter 162 | Chapter 165)
And then I guess all of Peter's henchmen at Grace Field in the penultimate arc either got to come over with the children or they fled the way they came in shortly after Peter killed himself (they had a few hours to do so before the children left for the human world later that evening).
