Carrie murders him.
She then continues to murder every Japanese patient that she can get away with until she is finally caught and, of course, being rather British about it, they decide to sweep it under the rug and just transfer Carrie away...
She continues to be with Billy, who is advancing in the military and then the war with Japan ends and Billy and Carrie have lunch with a military colleague and Carrie assumes that the next step is to subjugate Japan and is shocked when she learns that the Allies plan to instead try to develop Japan as an ally!
She argues with Billy and then Billy says something that just breaks her. He says that now is the time for us to learn to love them. It is too much for Carrie and she goes home and finally tells her full story to Billy, right before taking her own life.
Ennis plays the ambiguity of it all tremendously well. He's certainly not saying that Carrie is correct to become a murderer or that her views of revenge are correct, but at the same time, he also wants to make sure that few of us can ever truly put ourselves in Carrie's shoes, either. It's just a sad, sad state of affairs.
However, the main thing is that it was a striking, well-told story by two top notch comic book creators in Ennis and Snejbjerg.
All of Ennis' Battefields books are collected by Dynamite.
If you have any suggestions for February (or any other later months) 2009, 1994, 1969 and 1944 comic books for me to spotlight, drop me a line at firstname.lastname@example.org! Here is the guide, though, for the cover dates of books so that you can make suggestions for books that actually came out in the correct month. For the 75 and 50 year old comics, the cover date is three months ahead of the actual release date (so May for a book that came out in February) while the 25 and 10 year old comics have a cover date that is two months ahead of the actual release date (so April for a book that came out in February). Obviously, it is easier to tell when a book from 10 years ago was released, since there was internet coverage of books back then.
