No! You see a dog barking in a window near the end of the film which made me sad at first, but then I realised the dog wouldn't have survived that long on their own so someone must still be there to look after it.
Teacher makes a creepy comment to an underage girl, calling her beautiful. Clearly framed by the film as suggestive. He had also been watching her and touched her face while she was sleeping.
At approx 30:30, when Sloane is in the locker room walking past the shower stalls, she gets an alarmed look on her face and runs to a sink and gets sick (audio - the visual is just her leaning over the sink). Over in 6 seconds. A couple other spots during the movie it seems like someone may get sick, but this is the only time.
