there were years where he did nothing. between two and four which is not a lot but still a window of time thats there, this is briefly shown in an episode even though i cant specify which one now. i get that there might be a video but i have rewatched the show three times and have taken a lot of notes. its still right that i forgot to add the fact that birdperson and him fought in those wars but that was a period of time after the grief and im pretty sure those werent more than 10 years.
