I noticed you forgot to add a few question marks, other than that I love where this is going. I loved your portrayal of Derpy it really suits her in this situation. Worried though Anyway can'tw ait for the next chapter

Poor Dinky.
And everypony else, soon enough.

Like the story so far, a few grammatical errors here and there, but other than that, keep it up.

I really like the concise style you've given this story. It works well for this type of plot. However, there are times when you seem to rush it a little bit. That being said, you've really pulled me in on this, and I usually hate zombie stories. Good show, mate. I look forward to see where this will go.

Poor Derpy.
