>>22406062http://bulbapedia.bulbagarden.net/wiki/History_of_the_Pok%C3%A9mon_worldBW takes place "a few years" after Gens 2 and 4, which takes place 3 years after Gens 1 and 3.
During Gen 3, Wally was 10.
http://bulbapedia.bulbagarden.net/wiki/Wally_(game)N's age, from what I can find, is not known in any canon. While it's not unreasonable to suggest that he might actually be older than Wally, which requires him to be 13+"a few years", as N would have to be older than Wally for Wally to be a clone of him; it doesn't make sense to suggest that Ghetsis would clone N BEFORE the events of BW1.
