I wanted to take a moment to spare some of you from a much unneeded death while doing this quest. First of all this quest gives you a quest item which once used is supposed to convert your action bars and provide 3 options, a YES, NO and ABANDON button, but mine didn't. This, I'm sure of, is because of certain addons that I like others may use which breaks the UI. Regardless here are a couple quick suggestions to help you without having to disable your addons.

For the YES button make a macro with the following code:
/click BonusActionButton1

For the NO button make a macro with the following code:
/click BonusActionButton2

For the ABANDON button make a macro with the following code:
/click BonusActionButton4

Now you will be able to answer the questions if your UI breaks. Note that I had to use these macros again for a speech quest some time later in the same zone.
