Time passes, Shane and the Starretts fall into a happy and mutually beneficial relationship, and everything goes well. Did you notice that Joe left the homestead in Shane's care for several days, including his wife and child? It's not made a big deal of, since this is told from a child's perspective, but you know Joe must trust Shane wholeheartedly to leave his wife alone with this man for several days. And Marian must too, if she's comfortable doing so. Shane certainly is a special guy.
Bob gets some gunplay pointers from Shane at the end, and gets a tiny glimpse of Shane's past in the process. We still don't know much, but we do know he is uncommonly handy with a handgun, which implies quite a bit, considering he refuses to wear or carry a gun now.
"Listen, Bob. A gun is just a tool. No better and no worse than any other tool, a shovel -- or an axe or a saddle or a stove or anything. Think of it always that way. A gun is as good -- and as bad -- as the man who carries it. Remember that."
