For non-rogue below 90:

<The Black Prince looks you up and down.>

It is very good to meet you, <class>. You are one of the vanguard, it would seem - an explorer in a strange new land. And how have you been finding the mysterious continent of Pandaria?

You have the look of someone who gets things done. I want you to return to me once you've gotten the lay of the land.

I will be right here.

For non-rogue at level 90:

Welcome, <class>! My contacts throughout Pandaria tell me that you have been quite busy here. I admire mortals with your... 'initiative.'

History finds us at a turning point. If you are prepared to meet destiny with me head on, I will ensure that you are richly rewarded for your efforts.

(second part after chat bubble question, same for both)
Player: Who are you?

I have chosen the name "Wrathion." To my knowledge, I am the last of the black dragons.

My father was [npc=56173], the Wroldbreaker, the Aspect of Death, the Destroyer... But I hope you will not hold that against me.

I have no love for my father, whose corruption destroyed my race, or for the Red Dragonflight, who stole away and experimented on my egg to create me.

Let's just say, I am... unaffiliated. And I am always on the lookout for the like-minded heroes.

[class=4] gets special conversation:

Below 90 with [itemset=1088] or [itemset=1089]:

Hello again, <Name>, was it? Yes yes... I believe we left behind some unfinished business back in the Eastern Kingdoms. How you been finding Pandaria?

I have another assignment for you, if you are up to the challenge this time. I assure you the rewards will be worth it.

Before we begin, it's important that you familiarize yourself with the lay of the land. Come visit me once you have earned more experience here.

Below 90 with [itemset=1087]:

It is very good to see you again, <Name>! I trust the weapons I gave you at [faction=349] have served you well?

I have another "assignment" for you here in Pandaria. This will again require all of your skills, and again I assure you... it will be worth it!

Before we begin, it's important that you familiarize yourself with the lay of the land. Come visit me once you have earned more experience here.

At level 90 with [itemset=1087]:

I am glad you have returned <Name>! I trust you are now acclimated to this strange new continent of Pandaria?

You have already proven yourself to me in the past, so we can dispense with any sort of tests or trials. Let's get right to it.

Are you ready to change the world?

(second part after chat bubble question, same for all)
Player: What are you doing in Pandaria?

Certainly I'm allowed to have SOME secrets. Wouldn't you agree, <Name>?

I arrived shortly after the mists collapsed - I was able to fly here after my Ravenholdt colleagues learned of a naval battle off of these shores.

This land has been hidden for ten thousand years. I've only just begun to plumb its depths!

I have no love for my father, whose corruption destroyed my race, or for the Red Dragonflight, who stole away and experimented on my egg to create me.

So this means... that the egg you've helped [npc=46654] 'secure', in the quest chain that takes place in the Badlands... hatched to become Wrathion.

Wow. That's incredible.
