If you kill the rat that is getting chased by 3 children in freeside 2 of them start to eat it and the other turns around and walks away.
That's odd because as far as I know, there's two kids near M&Rs, Max and Stacey, and one kid who hangs out at the corner between the Mormon Fort and the internal Freeside gate. There used to be two of them but the girl was cut for some reason with the last patch, he's the only one who chases the rats and I've never seen him interact with the other two.
And he's still eating rat. Which is odd because he sleeps at the OMF and I'm sure the Followers would feed him.
