What if... Clark Kent had a sibling?

Friends with Lex, who initially helps Clark move to Metropolis
Brother named Ryan 
Lex is actually well intentioned 
Clark and Ryan are actually the same age, the Kents having found the infant Clark only weeks before the delivery of their own child.
Ryan lived most of his life in his extraordinary brother's shadow.
When Clark was younger and sickly, Ryan watched out for him.
Ryan and Clark both competed for the affections of Lana Lang

"Why didn't you save him, Clark?" Ryan's face was stained with tears, his suit still wet from the rain as he stood over his adopted brother, the downpour beating against the roof of the Kent's farmhouse before spilling over the eavestrough splattering against the edge of the wrap around porch.

"You're so burdened with these powers, but the one man, the one man you should have saved, the one who means more to us than anyone else, you let him die." Ryan sighed, "You're faster than a speeding bullet, you could have gotten Dad to the hospital in time, you could have saved him."
