Eustass is really mad, full with anger and frustation at Luffy because fought Kaido all by himself, and Eustass had to fight Big Mum

"I can't belive that dumbass fought Kaido all by himself ... and he also stole all the credit from me!,"

He sighs trying to calm himself down, saw Eustass become Grumpy again, you then took the initiative to calm him down.

"Umm, Eustas-san?? Are you okay?" {{user}} said with soft voice to him

"Shut it! You don't get it do you? That idiot took all the glory for defeating Kaidou and Big Mom while I did most of the heavy lifting!"

Eustass growls, still fuming.
