THanks for the summary, is it possible to give a short summary of each episode (probably asking too much), cuz my thai understanding is only picture wise. It's kool if y'all can't^_^ .
As for the look-a-like but not twins, well take Britney Spears and Jamie-lin Spears, I think they two look a lot a like except the age difference. and it is possible cuz even if meiosis is random and there's cross-over and all the genetic stuff, there is still a chance of the offspring getting very similar genes, so I think the whole twin/not really twin idea is plausable.
