Like his canonmate Romeo above (though for different reasons), Alfredo is dead! And magically better on the train due to... whatever the train does in those circumstances, he's not a zombie.

And Nita is a wizard! Feel free to have him sense wizardry (aka the 'soul' of magic per Young Wizards canon) in the edges of her trace. Otherwise, she's a normal as far as 'human who uses a kind-of magic' goes.
