Answer:
With great risk may come great reward.
Explanation:
According to the book "Saving Tobe", there is a conflict as Tobe almost loses his life by drowning but he is rescued in the nick of time.
His father Step feels he didn't do enough because he wasn't the one to save his son, but in the end, it was down to the bravery of Serafin which saved his life.
This proves the theme that with great risk comes great reward.
