Telling me about reading manga 😂
Whitbeard crew members talled Ace that they agree and Blackbeard should pay but Ace shouldn't go alone, he should hold on cuz Whitbeard had bad filling about it. The only reason Whitbeard stopped Ace was because Ace wanted to kill Blackbeard by himself, he felt responsible since Blackbeard was part of his division, he was under Ace. Whitbeard new samthing about Blackbeard so he didn't want Ace to go alone but Ace insisted. When Shanks came Whitbeard said him that he's going to kill Blackbeard.
Do you really believe that Whitbeard wouldn't be able to stop Ace if he wanted? Ace couldn't escape Whitbeard's ship while trying many times and he managed to do it back then? Whitbeard himself wanted to kill Blackbeard he just didn't want Ace to go alone.
Read the story properly.
