And now you know we spent quite a lot of time on Heinrich becoming Fritz, so there was no way I wasn't going to notice that and remark on it :D

Yep, exactly. As soon as I saw that, I knew you were going to pick up on it too, after all that time betaing/co-authoring.

Mildred said yes, but otoh she wouldn't mind reading stories where he does, and/or the time wars between Fritz and Heinrich.

Time wars between Fritz and Heinrich...???? !!!! this is a thing I can have? YES PLEASE where do I sign up????

Lol, your reaction is much closer to my reaction than the sedate summary by Selena. My actual reaction:

Selena: also, one does not want Frederick the Great to find out about time travel.

Me: The part of me that has rational political beliefs: No, of course not!

The part of me that is fannish: OMG YES WE DO WE EXTREMELY DO BRING ME MY POPCORN WOULD READ ABOUT THIS ALL DAY LONG GIMME!!! :D :D :D

Would also read the time wars between Heinrich and Fritz!

And yes, Fritz+MT time wars too! Would read!

although I am going to bet my hat (except that I had to eat it when it turned out mildred was the author of Corporate AU)

ROTFL!

Well, you may keep your replacement hat, because my reaction to *this* one was:

ONE of these two options you are allowed to gift me. :P
