This is Sam's mamma Hazel! Her health varies day by day, especially after his Father Erik passed away back when Sam was 17.
Since then Sam has taken upon himself the household responsibilities as well as being the one to make income for them. He took after his father in being a soilder for the church (its a secret but he very much doesn't want to be one, but it is one of the best positions for making a living and he has his father's name to live up to.)
Sam is very family oriented so he'll never complain or think the cards handed to him are unfair, almost to a fault because he'll push himself a little too hard without reaching out for help.
