That's an interesting wrinkle, actually. What if Clark/Superman is so fond of Jimmy because he was an old friend of his brother/father's? Perhaps he feels responsible for it too. Superman as surrogate father, or "Big Brother", to the orphaned Jimmy, as opposed to "Best Pal". While the Smallville Season 10 comics were pretty great, they still showed Superman's early career and did not allow for that kind of "10 years on" development. What would the "veteran Superman" of the Smallville continuity be like?
