Everything that she had was not brought with her and was kept in a safe place, while she only brought a list of what was there.
Perhaps the list was not complete, and there was more that would be quite valuable, but it was enough to show that Ash was being smart with her approach when she had such things to negotiate with.
If she just gave all of it to a middleman, then it would not be guaranteed that such a person would not be able to hold back their greed, especially when they would only have to hand over what was related to the task.
If Ash were to give over everything just like that, then it would not be very smart.
It would have been better to bring it to the current meeting with Ross, but it was still best to remain cautious and not bring everything out all at once.
If she showed up with everything by herself, then it would not be so easy for her to negotiate.
