After you have Looker arrest the last sage out of the Seven Sages, He should thank you and he should also tell About a Boy who sounds exactly like N, who has been seen with a dragon pokemon somewhere far away... ^_^
looker only comes when you beat the game and he gives you a Super Rod and you meet him when you find the seven sages.
The is nothing else to really do. The seven sages were basically the final mission.
He says he is going to a distant place to look for a legendary pokemon, but he doesn't give you anything.
i have been on several official cites looking for this including Pokemon wiki and serebii they list how to find the seven sages but not ghetesis so i think you cant sorry
route 18
He goes back to sinnoh

When you finish finding the seven sages looker comes and tells you about n ps he does not give you the liberty pass
You don't.
Yo mammas house
looker only comes when you beat the game and he gives you a Super Rod and you meet him when you find the seven sages.
Looker went asking the seven sages about their plan and after that he went back to sinoh to do some resreach. He will come back after you get all the 3 legendry pokemon Virzion, terrakion, and cobloin. he will blab something about your legendry pokemon and after that i dont know.
N's location in the end is a mystery; after finding all of the Sages, Looker tells you that there was a report of someone seeing a dragon with a boy in a farawat region. What region, however, isn't mentioned.
