This is from another story on FF.net, "Sherrock Town". Bugs was the New Yorkese merchant who took that wrong turn at Albaquerque and got himself mixed up in the rebellion against Mayor Sam. Lola was a prominent player in the rebelion, Bugs just didn't know to what extent...(Read the story if you'd like to know what I mean...)
in the pic (Not from any particular scene), Bugs is wearing the 'Jim West' type of ensemble (note the 'BB' on his buckle). Lola is in her final costume, with a Native American twist to it.
Hope ya like!
