- Kaidou was pissing his pants, because it would be an all out war if BM landed in Wano lol
- King and Queen were neither in cells nor did they had handcuffs on them - peak headcanon right there.
- King and Queen attacked him and GB even told them to stop, but they didn't listen.
If you wanna shit on someone then use actual manga panels and not your headcanon.
I can see this fear of Kaidou when he decides to release Big Mom, his anger is derived from the fact that he is not at all prepared to face them, which is different from fearing Big Mom, Kaidou released Big Mom that was under your command control, to kill her in a 1 on 1 confrontation, the only thing that's screaming is not your fear, it's Kaidou's overconfidence in killing her.
There are two different situations here that you should consider.
1st - Scenario she was not alone.
2nd - Scenario she was alone and we saw what Kaidou did.
How funny, Green Bull asking Queen and King not to react or try to counter their attacks.
What should they do? Wait for Green Bull to attack them and they're paralyzed looking? LOL
They need to somehow deal with the attacks, as their main combat tools are broken, and one of them is missing one of his wings.
In addition to being recovering from injuries received, just like wano heroes and retainers.
