Hiems and Cygna

So, with his current (near as I can tell) Perdo 11 and Ignem 9, when they spend the night together, by morning she would be chilly, but like "need to close the window" cold and not "Holy moley, I can't feel my fingers!" cold? So, it looks like she still has plenty of time to work on her remedy, get her Ignem up...which should also provide a Form bonus against his coldness, right?
