So, after playing up to a certain section of HF last night (and after reading this piece I think you'll all know which section I refer to), I sat down and typed up this short bit mainly by emotion. I admit it's pretty much my own wish for how things had gone instead of what really happened.
So, yeah, "Saber lives" situation here. I have to admit I don't know if she could have escaped the shadow even if she wanted to, but it was something I felt like writing.
I'm debating on doing further parts; mainly to show Shirou's reaction and possibly Sakura's. I can't see this being very long, considering that I haven't played far enough into HF to accurately retell the story from the "What if" of Saber surviving.
