Cry only gave a light warning for how serious the situation was. People could have died. "Karen" like behavior is justified in this situation.Excusing brat behavior with "he/she's just a kid" Is a typical karen mindset.
And to got the guts to even get mad to someone that warn the kid is mind boggling. With how long Ark know Cry with all the bullshits he says that somehow always come true. Even from ch 1 all the member know that Cry never give them the full picture, but it's wiser to follow his word. Ark here just decide to ignore it knowing of all that.
As an asian if i was act like a brat and didn't listen to someone that warn me of a danger my parents would become the danger for me. before i hurt myself.
