At this point I think we want the lesson to finish up something like this:

- Dracula and Mummy approve the final changes.
- Someone pushes the merge button on GitHub and deletes the `shelter_plan` branch there.
- Wolfman pulls the new `master` branch down from GitHub.
- Wolfman deletes his local copy of the `shelter_plan` branch.

This distinction there being that the merge happens on GitHub and not locally. (Forgive me if we haven't concluded to go that direction.)
