idk how to find the last scene in the first line , but the next two of them u'll find if u go to the toilet in the afternoon.
When you go to work in the morning everyone is there "working" (because it's just you and Ursa), then, when the afternoon shift starts (or even before it) you notice that's missing someone, and if you go to the toilet (the door upper right) you'll find Jane. Now the rest of it is just spoilers, so go there and find for yourself 🤭
