Ok, so i think the good Tms are gonna be After the E4. Thinking on that though, let's consider all the things we KNOW we have to do. Leaders:8 more, So,Seeing as there are 12 episodes and 10 leaders in game, it's a fair bet that there will be a few "meteor" episodes, dedicated to fighting the scourge of reborn. I'd personally say min 3 epsiodes dedicated to this.so, if you can do math, that's 11 more episodes estimated. 11. just to get to the E4, then theres the fact that even the E4 battles may not go interrupted, Fpr example pokemon Black where your challenge was interrupted by N., and who says the games story ends there?The E4 is by no means the end of Reborn
Long story short, we have a LONG, LONG, LONG, LONG, LONG, LONG, LONG, LONG, LONG, way to go before we even get the possibility of good TMs.
