I'll ask this in the least spoilery way that I can think to do…
This certain quest is one which allows you to get a certain mount that resembles a stingray.
You are asked to go to a certain someone (person A) and get a certain something, then bring it to a certain other someone (person B). Yet another person (C) is mentioned also.
What if I gave the certain something to that certain someone C rather than someone B?
All I'm looking for is a yes or a no: Is there only one way to get this certain mount in this certain quest?
