This one-way time-traveling adventure continues to dive further into history, as everyone's favorite foils, James Rison and Simon Magus, join forces with another pair of Agents of The Sing, in Tombstone Arizona, to ensure that the shootout at the OK Corral is Future Proof! Meanwhile, the enigmatic Umbrella Man comes face-to-face with his younger self when he revisits the JFK assassination and proves that the future is a thing of the past.
Some parts of Future Proof--like this issue--feel like those in-between moments where the writers let the story breathe by bringing in other elements that just add a little color, or that completely add in a whole other angle for readers to think on. Both are done in this issue to good effect. Also, the art is still nuanced in bringing in the taste of the period its featuring, which I love--as well as the famous historical quotes that are sprinkled throughout.
