Shu : oh I found this in your garden between the bushes she was hungry and weak so I bring her here with me...
Oak : that good but I never saw this Eevee in my garden before maybe she is wild and come inside my garden accidentally...
Shu just nodded and didn't share eevee story with oak because he knew he would be considered crazy if he tell eevee told him about her past...
Oak : well than let me take it from you...
When shu was gonna give eevee to oak she wake up than hop on shu head like she didn't want to leave him...
Oak : oh look like this Eevee got attached to you shu I don't think she wants to come with me...

Oak : he got his Pokemon at age 3 only I know he will become great...
Delia : yeah I hope so...
Outside
Shu was jumping around happily with eevee in his hand jumping here and there he got his first Pokemon and he is one step closer to become Pokemon master...
When he was gonna show Ash about his Pokemon he saw Ash with Gary arguing over something shu who don't wanna become a part of their argument go near the the lake and lay down their with eevee sleeping on his chest...
Shu pov

At professor oak lab
Oak : Delia can I ask you something...
Delia : yes what is it professor oak???

Delia was now shocked to hear this but seeing professor oak is serious...
Delia : I don't know but he is just a child...
Oak : yes but with exceptional thirst of knowledge I know when I see one if he got proper knowledge he can be like Red and Blue....
Delia was shocked after hearing Red and Blue name from professor oak mouth...
Delia : I know but I am scared after Red beat Blue and become Kanto champion Blue suddenly disappeared and never come back after that Red also resign from being champion and disappeared just like Blue and after that no news came of both of them what if shu also disappeared like them...
Oak : they were both legendary trainer who were unstoppable they Pokemon were strong enough to beat down legendary and mythical Pokemon but they suddenly disappeared...
Professor oak started crying...
Oak : I searched for them I searched for them in all region but couldn't even find a trace about them it's like they never existed from that day onwards no one became Kanto champion cause no one ever beat down elite four but I can surely tell shu has same potential as red so I wanna make him my lab assistant please Delia...
Delia who knew oak is serious says yes but shu will become professor assistant at Age of 5...
