Arnold wanted to visit this 'queen' these humanoid monsters were talking about, but he wasn't there alone. He couldn't act without the consent of the others as he was there as their leader, not some vigilante. Moreover, if he agreed to an alliance without thinking of the consequences and things end up going south then not only his reputation but also his family's reputation would be torn apart.
This he couldn't accept. The Blacks had helped him and Nicole when no one else did. He couldn't let their hard-earned reputation go to waste because of his mistake.
The nagas were still expecting an answer from him, but he had to discuss things with the others first. So, Arnold asked the nagas to wait for some time, while they decide on how to proceed with their request. No one expected the nagas to oblige with their request but they did.
"What do you guys think?" Arnold asked the others once the nagas were out of earshot.
