Hold back anything? Like what? Oh, that's right. Maybe her death, for starters. He hesitated. Then he moved to the chair opposite her and took a moment to consider his options here. He could lie. Refuse to tell her the truth. Or actually tell her the truth. Either way, Sam figured that she'd learn about it sooner or later. The truth, that was. Who better than to hear it from than her own son?
"Do you anything about a demon named Azazel?" Sam finally started, looking at her directly. "I mean, do you recognize the name? He has these yellow eyes..." Sam trailed off and hesitated again. "It all starts there. With him. He kind of came to me when I was a baby." And poured his blood down Sam's throat. "Snuck into my nursery. I guess you walked in on us then, because he..." Killed you.
A pained look crossed over him then. Sam really didn't want to say it.
