She was standing in front of Nine's room with Zero Three beside her.

It was time for their daily patrol yet the blond Valkyrie has yet to show up so they came to look for her.

The two looked at each other having noticed how strange Nine's tone was.

"That's what we want to ask you." Zero Three asked, crossing her arms. "It's time for work. We're gonna be late."

There was no response for a long ten seconds and the young Valkyrie's frustration began to grow, but then nine spoke, her voice sounding a little bit better.

"About that… since Three got a pass for yesterday, Doctor had given me permission to sit this one out." She said. "You two will be on your own today. Be careful out there."
