Quotes: Thicker Than Water

I will not try to turn a son (even mine) against his father, no matter how estranged to two are. Blood relatives can be annoyingly sentimental.

Thor: We've looked for you a long time, brother.
Loki: [clearly exhausted] Stop. Stop calling me that.
Thor: But, you are.
Loki: I can think of more fitting appellations. Traitor, criminal, Jötunn, monster
Thor: [firmly] —brother. First, and always.

You tell me you ain't did it, then you ain't did it,
And if you did, then that's family business
Kanye West, Family Business

My brother and I have our differences, but I would never attack him.
Tonraq, The Legend of Korra

Family supports, back each other up. Accept the inconveniences. Sometimes that means a mom wipes a baby’s ass, even though it’s gross and boring. Sometimes it means you give a brother-in-law a place to stay. Sometimes it’s just a listening ear you wouldn’t give to a friend, but you have to give to them because the bonds are that tight.
Blake Thorburn, Pact

Never turn your back on family, even when they hurt you. Never let life get the better of you. And if you remember nothing else, remember to find time to eat together as a family. Even when times are rough; especially when times are rough. There's no lack of painful things in this world, but hunger and loneliness must surely be two of the worst. Thanks to you, my precious family, I didn't know a moment of either of those the last ninety years.
Sakae Jinnouchi, Summer Wars
