I'm not. I'm fourteen, sir. Nearly fifteen. It was 1850 before I got here.
[speaking more quickly now] But Papa, you needn't spare me. I know things. I know about '53, about the fever and what happens to poor Cygnus if I cannot stop it when I go home. And Sirius. He's alive here. He's seven and as he's concerned it is 1852 and...please don't tell him any different, about the future, just let him be happy to see his grandfather. He is too young to burden with our troubles. I have kept him safe from that.
