Once an Assassin, Now a Royal Nanny Chapter 11 Recap: Assassin Instincts Face Royal Childcare Chaos
A sudden shriek from the child makes Rachel twist sideways, her foot sweeping crumbs aside like debris on a battlefield. Dinner clatter pauses as she blocks a flying spoon without looking. The duke watches, eyes narrowing at the way her fingers tense—too fast for a governess. Silence stretches until laughter cracks it open again. A napkin dropped becomes a signal he files away. Every move now feels studied, even when pouring tea.
A whisper of talent surfaces in Prince, sparked by Rachel’s odd routines. Her way of teaching—unlike anything seen before—builds a quiet trust between them. Danger creeps close, though, shadows from her old world reaching out. Each threat tightens their connection, not by choice but necessity. Moments of calm feel fragile, like glass held together by breath. A quiet moment in the kitchen hides sharper intentions beneath. While laughter echoes near the hearth, glances linger too long across corridors.
