The new Order is feeling under the weather, and Gemma looks dog-tired.
In French class, Gemma can't respond to a simple question and Mademoiselle LeFarge becomes angry that she is being mischievous and not speaking in French—it was only two days before that she spoke it perfectly.
Mrs. Nightwing tells the four girls to walk outside and get fresh air.
Gemma tells them about Sarah being alive and they search the school for the photo from 1871.
They can't find it, but then Gemma looks at the photo from 1872—it's all wrinkled—and finds the 1871 photo behind it.
Sarah's face is unclear because she turned her head… but the photo of Mary Dowd reveals that she's Gemma's mom.
