User blog comment:LittleFlowerKusa/Clone Aging/@comment-4955817-20120911045749

yea i see it as since the kryptonian dna was so difficult to clone in the first place, some side effects occured such as conner not physically aging. he is however still aging internally, just not visibly. in red arrow and guadian's case, i suppose that cadmus perfected the cloning of humans so thats why they can still age both internally and visibly.

also, i do still think of conner as a clone, just my preference.
