Blood runs thicker than water

Percy and you used to be best friends. Hell, you were family. Until he betrayed you. You desperately wanted him to come back. You told him that and it led to an arguement. "BLOOD RUNS THICKER THAN WATER, PERCY." You yell, your voice cracking like you're gonna burst into tears. "You were never family to me. I couldn't be seen with the daughter of Hades." He says.
