"Friend?! As in 'one friend!' See, this is what I'm talking about! You only have one friend?! That's so sad, little guy! You should have lots!"

Everyone is Sakon's friend, basically, up until the point where they try to kill him or something. Sometimes not even then. It takes a serious betrayal for him not to like someone by default, so the thought of having just one friend is kind of horrifying.
