River chuckled, nodding her agreement.
They had apparently underestimated Hanako's hearing. Her ears flickered toward them and she suddenly spun, clapping her hands together.
"Oooohhh oh oh oh, I knew it! I didn't wanna say anything but I knew it!"
She suddenly darted forward to grab River's hands, bouncing excitedly on her heels. "Officially congratulations! I knew I smelled something on you!"
"Wait, no, I'm not—" River started to correct her, laughing, then suddenly drew herself up short. She smelled something? But...okay, it was easier for someone to smell a change in hormones that wasn't in their own body, but surely she would have noticed...something...
She started counting backward, frantically doing math. When had she last bled? Four, five, six...
Oh dear.
All the color drained from her face, and Hanako looked between her and Kah, puzzled. "Ahhhh...I'm sorry. Was it supposed to be a secret?"
