This is good. Enjoyable - good emotion and interesting case-fic. Written well to especially considering English isn't your first language.

Very nice story. Definitely stayed close (if not perfectly) to canon. I'll be checking out your other stories.

Gosh, I'm so happy I found this, this was exactly what I was craving after watching the show :)
I really liked your characterization and the detail about the case and the medical stuff, that kind of thing makes a story so much more believable to me. I especially liked how Casey deals with fearing for Walsh and that little conversation between them about his family and why she's his proxy. Really good job!

One advice-ish remark, if I may: I've noticed that the articles ("a" and "the", I mean) are missing pretty frequently, and thb that brought me up short just about every time while reading (I have a tendency to re-read sentences if I think there's a mistake, I can't seem to help it). That might just be me, but it might bother other people too, so perhaps you might pay some attention to that? It's always a shame if formal stuff like that takes a tiny bit away from the quality of an otherwise good story.
Right ... I hope it was okay for me to point that out!

As I said, I really enjoyed reading this! Good job!

amazing story. i really wish there were more Walsh h/c fic out there.

and i cant even tell its not betaed. Great Job!

wow. I enjoy so much your story.

the chapter 1 is great, the chapter 2, as you said a bit dramatc and still good.

BTW: for my taste you‘re a good writer :)
