new rebattles

i think in next update we will get some more npcs to rebattle but my question now is ..... how can i get the number of one if i battle him before in older version ? or will you add an option with which we could ask them again for the number ?

I had completed the game before the rebattle mechanic was added. All you have to do if talk to the trainers again and they will give you their number.

ok nice
i thought it wasnt in the game yet
