Here's my reflection on the third arc of this series.
This story arc ran for six issues, published from June to November of 2011. Here are my impressions:
One of the opening scenes, with the displayed coffins of convicted and executed criminals, really helps to set the scene.
We meet the Mystery Mummy, a character who was already foreshadowed earlier in the series. He even receives a whole issue for his back story.
The attack by bandits against a train definitely checks one of the “What Do I Need to See in a Western Adventure” boxes.
This arc definitely showcases how interesting many of the characters are. We can have separate, parallel stories for Becky and Gord, and Drake is missing, and it's great.
Along that line, the two elements of the Sixth Gun (for Becky) and a haunted house (for Gord) allow for some really intriguing moments in which those characters meet others who are long gone, and even themselves.
