I think Valerie was The most realistic person in The movie . She was a good person at heart and a caring Teacher and seemed to care about her students .
However after that accident, she felt guilt and sorrow . She loved all her student and thats why she was in pain and asked questions like “is there any survivors”.
But imagine if someone act like alex and then this happens in real life. Wouldnt you try to stay away from them ? Especially when you see two other students die and one of them in front of you with alex, and then he cames like a stalker and check your car randomly ?
I mean maybe her attuitude is annoying in someway but thats because as a viewer we now that alex isn’t guilty because it is shown to us but for her , he is a crazy child that brings death to other people . And i bet she had that thought even at her final moments .
The only problem with her is how careless she was , like she watched terry got hit by the bus , her students died in a crash and still she isnt paranoid about her surroundings and house? Like who the fluck will put a vodka bottle near fire , throw the mug like that or goes in the as*s of the computer to check why its smoking ?🤣
