"Question for fans of Detective Pikachu: When Tim inhales the R gas why can he understand Pikachu and not other Pokemon?" Detective Pikachu was a great bit of nostalgia for me. I finally got to see Pokemon in a non animated film, Mewtwo made an appearance, and it was was very funny. But something has been bothering ever since I first saw it in the theaters. I assume we all remember when Tim accidentally inhaled the R gas right? Immediately afterwards he begins to understand when Pikachu is saying, however he does not understand what other Pokemon are saying. Now we know that the R gas made Pokemon act all crazy and deranged, but how does it affect humans like really? Is Tim able to understand Pokemon now, or is it just with Pikachu? Does it affect other humans the same way, or does it vary with each person?
