Yea. And to see how much of a bond your character has with that Pokemon. Basically their history. I told her that Gar feeds off the negative energy/emotions from her trainer as a source of food, and to help Shade cope. Funny story, behind that. I was planning on making a story, where some plot thing was a thing XD don't remember, but Gar ended up eating Shade's nightmares to help her sleep. Since he couldn't distinguish if it was a dream/nightmare by taste (because dreams taste like something XD), then he decided to keep eating all of her dreams. She would rather go through fear-crippling night terrors than to lose the ability to dream, so they compromised to eat her negative emotions instead. Which could result in a very cruel Gengar, seeing as how they are quite emotional at times.
