Anybody else noticed that Bonnie seemed to be able to sense Puni's presence and how it was feeling?
Maybe the writers brought up the whole Bond Phenomenon thing during that set up episode because Bonnie and Puni have that going on?
I think only be a convenience for the protagonist group to locate the location of Puni-chan without wasting time on explanations but was to found in past episodes of this season when ties trainer-pokemon (when Bonnie meets 10 the starter it will be a Zygarde, LOL) are very strong can get to communicate, understand or feel the closeness or distance of each other. An example is Diantha with Gardevoir and Korrina with Lucario, although in these cases was due to the phenomenon of mega-evolution is to insinuated that Zygarde (at least in the anime) has to do with the mega-evolution so technically it could applying the same situation with Bonnie and Puni-chan.
