While waiting for Clay to return from his work, and after training, Ash and co. got a surprise visit from Cilan's brother Chili from Striaton City, who's apparently on a journey of his own and training since he came all this way to get here. Turns out he wants to be better than his connoisseur brother after always losing so many challenges. So he decides to put his skills against Cilan by having a battle as Chili use Pansear while Cilan use Pansage. Who will win this sibling rivalry? And can Cress be a good Gym Leader by himself in Striaton City without Chili?
There was a moment from when Chili's Pansear was training and after that he runs up some stairs, though that moment has been done before in the movie "Rocky".
Some similarities to the Rocky training montage comes when Pansear, runs, does one-armed push-ups, sit-ups on a bench, and punches a fruit in the tree
The dubbed title originated from Pennsylvania, known as the State of Brotherly Love, which was the setting of the Rocky movie that took place in Philadelphia which is located in Pennsylvania.
