THE SNOW QUEEN TRAPPED TONY WITH INFINITE DECIMALS. HE DEFEATED HER WITH PI. That may be the greatest thing ever. I loved the image of the vast frozen floor carved with spiralling numerals - that would make such a fantastic splash page. And I loved that what freed him was the mess and horror of spilled blood interrupting the perfection of metal and numbers - it's kind of Tony in a nutshell, there.

Gorgeous, satisfying fic, and I enjoyed every chapter of it. Thank you. :D
