Mnemonic

Your mom shoots an arrow at a mannequin holding a spoon—but the mannequin dodges! Now mom is seized by doubt. Was that thing ever really a mannequin, or has something alive been standing in her living room this whole time?
Additional thoughts
Picture mom's wide eyes as the mannequin sidesteps the arrow, spoon still in hand. The uncanny movement is what sparks the doubt—nothing should move like that unless it's alive.
Quick recall
Mom fires an arrow at a mannequin gripping a spoon—it dodges, flooding her with doubt.
