As a foil, what characteristics do the actions of the cheery soldier point out in Henry?

The cheery soldier helps Henry back to camp after he wanders in, after running away, to camp all disoriented and despondent. The Cheery soldier brings out Henry's inexperience in battle. While the cheery man knows his way around, and perhaps knows exactly what Henry has done or been through, Henry has no clue where to go or what to do. We see opposites of experience and attitude. I think the cheery man has the disposition and experience that Henry strives for. We finally see more of these traits in him by the end of the book.
