First, I enjoyed the second geek session so much, guys. It's so much fun listening to you both, it was really awesome 🥰
Second I'm the one who suggested that Kakashi likes to sit on top of Minato's head and that's because we did see him in the anime go and sit on top of the Hokage mountain when he's sad, I don't remember the exact episode but it's where these screenshots are from, he was sitting on top of Hiruzen's head here but I thought that maybe after Minato's death he started to only sit on Minato's head, we've also seen him in that episode before the famous race with Guy in episode 219 talking to Minato's rock face so he's definitely has some sorta connection with Minato's head on the Hokage rock
