Episode 3 marks a step down for Chaos;Child. Kurusu isn’t dead or even injured gravely enough that she would have to spend the night at the hospital. At least her being attacked provoked some emotional reactions from Takuru, so it’s not a total waste of screen time, unlike the confrontation between him and Kawahara.
Kawahara is right to criticize Taku’s carelessness. Even though it’s hardly his fault that his foster sister got stabbed, he still bears responsibility for dragging his friends into a danger he clearly underestimated. Still, Kurusu’s suitor loses all credibility as her shining knight when his response to her getting out of bed and collapsing from reopening her wound is to leave the room instead of rushing to her side or, much more sensibly, call a doctor.
