WeiWei would be safe.

Since WeiWei was up in the arms of Li Xue. So, the moment Li Xue winced and her body stiffened, the little one felt it. All this while even though she has kept her eyes and ears closed, the little one had the inkling that there was something wrong around. Otherwise, her Mama would never stand and wouldn't wrap her arms around her when she sees her crying. 

She would never ask her to not ask questions. Her Mama has always encouraged her in asking questions, so restraining her today was too different for her to notice easily. 

Also, when her Mama came to hug her earlier on the chair, she felt her body trembling slightly. Knowing her mother best, she knew her Mama only trembles when she is either crying or angry. Since she heard her speaking, she must not be crying but rather angry.
