"Your-" Bryony stopped, uncertain what to say. Wordlessly, she stepped closer to Marcus, letting his hand fall so that she could tuck herself in against his side with one arm looped loosely across his lower back. If she didn't know what to think, it must be worse for him. For a moment, she fell back on her upbringing and - too well-mannered to pry into another family's affairs - focused on the part she could deal with. "It's not your fault you didn't know," she told him, looking up to meet his eyes with a surprisingly set expression. "Someone should have told you, and they didn't." Anger rarely flared up in Bryony, but if anything was going to set it off it would be anyone doing wrong by Marcus.
"They could have told you that's why they didn't want you to go there. You were old enough." By the time Bryony was old enough to be allowed to toddle around without adult supervision, Marcus was already in double-digits. And even if they hadn't told him then - surely when he was an adult? "It's not your fault," she said again, because in that moment it was all she could hold onto. Her anger wasn't helpful, it couldn't change anything, but at least she wouldn't let Marcus blame himself for this.
