Failure. Not being able to see a patient recover. I know I seem like I have body of steel and a heart of iron. I remember the soldiers that were lost as well as the civilians. It's not a wound or disease that can be cured, that pain.

[No. Sentimentality wasn't a weakness. Nightingale couldn't show such anymore but that itself was a failure on her part, not a strength.]

So I push it aside and move on. I needed to do it in my life otherwise no one else would have pushed ahead. That conviction is the madness that makes me a Berserker. I don't regret doing so but it's not something others should do. I can't blame you for your sentimentality and it's not something you should blame yourself for, either.
