TMA fic: Last Edition

I started writing this over a year ago. I finished a first version, but wasn't quite happy with it and never posted it; and then TMA #167 came out and I immediately realized what I could add to make it better.

Last Edition
2.2k, gen, spoilers up to #167
Summary: Gertrude and Mary have one last conversation.

I must have listened to "First Edition" two dozen times trying to get their voices right... At least I find it easier with an audio source.
