Headcanon - At times Sokka would go to the place Momo was burried and leave a few fruits, especially peaches, the same thing Momo had brough him the day they met. Just because that was the beggining of their friendship and earned him his name (since Momo means peach).
I loved how Sokka and momo became close throughout the series. It’s adorable.
pow right in the feels..!
