That's my number one screaming plothole in the hole movie that I can't ignore - why didn't they just immediately call 911?
Evan and his girlfriend gets into an argument, and at one point he takes a step towards her and she steps back quickly and falls and hits her head. Why wouldn't you call 911 for help? Is it because they had done illegal drugs so was afraid of the consequences for that, whatever that may be? If you had done illegal drugs, and something happens to where your sister or daughter is not moving, would you not call 911? And how can you even assume for sure they're dead? You're not a medical expert, even if the person doesn't seem like they're breathing, wouldn't you call for help just for any potential life saving techniques? Wouldn't you EXHAUST the possibilities instead of assuming the default position of, "they're not breathing, must be dead." Again, imagine if you find your daughter lifeless and not breathing, are you going to conclude that they're dead, or go to the ends of the earth to do whatever you can to save them (call 911)? You have no idea what methods or techniques are used, or what miraculous thing might happen.
Also, tied for the most annoying thing in this movie is the fact that Evan doesn't actually clearly tell his friends watching on video chat, "no, I didn't do anything, she slipped and hit her head." Not ONCE does he say this in this critical time. He passively mentions it much later in the movie, but at this time when some of his friends are sort of suspecting him, or just generally unsure of what happened (since they only heard it, and then saw the aftermath), he never actually says anything to clear up his name.
The type of excuses he's giving are the kind you'd give if you did accidentally go a bit too far, and now are unsure if you would have legal liability. For example, if he had sort of brushed her off or dislodged himself from her if she had been getting physical with him, etc. Yeah, that I can see. Because technically your physical action of shoving them off made them fall and hit their head and die, apparently. But nope, he literally did NOTHING here. And this idiot not only doesn't deny it, he also doesn't call for help, AND he goes running off into the night like some lunatic, as if he's already a known fugitive. And unless I missed something, even though I thought people weren't allowed to be driving during the quarantine, his friend clearly was, so why was Evan driving as if was afraid to get caught? And his friends are not any smarter since none of them brought up the points I brought up.
Also, the whole argument that started this off was unrealistic to me. The girlfriend admits that she had a threesome in high school, and the boyfriend, Evan, understandably gets a little upset about it and can't stop asking her about it. Then, a bit later, two of their friends on video chat starts getting intimate with each other before finally shutting off the video. When the video is shut off, Evan makes a comment about how it was just getting good. She takes offense to that (for some reason), and he claims it was a joke. The girlfriend's mood was completely unrealistic here. She had no reason to even feel unhappy, LET ALONE mad. Doesn't this sound confusing even reading this? You're wondering, "wait, she's mad? About what?" Yeah, my point exactly. Her whole mood DARKENED after the comment Evan made about the two friends that had been getting intimate on video. Ok, that's weird, yeah, but why would you be MAD at him for saying that, or mad at him for joking about it (whichever way you, as her, would've interpreted it). You might be playfully disgusted, but not the piercing anger she showed towards him.
Along those same lines, when he got mad at her for keeping the high school threesome she had a secret, her reaction to him is all wrong. Just put yourself in her shoes. So now your boyfriend is really upset about this news. Wouldn't you react more like, "hey, this was a long time ago, come on, it doesn't matter." Not exactly pleading with him, but just trying to maybe "bargain" with him to get him to see your side. Instead, she's taking OFFENSE to him being upset about the threesome. It's just not a natural reaction to me. You don't get OFFENDED at someone being mad at you, at least not at this point, and especially not with the way it was presented (on a tiny, tiny, level, there would be a super tiny bit of flattery you'd feel because someone is upset/jealous, which is rooted in how they feel about you. I think we all know that feeling). So given that, you'd almost playfully wave it off (secretly enjoying maybe just a little bit, that this person is jealous). However you might personally respond, turning cold, dark, and hateful is probably not what most of us would do.
