Double Dialogue! Not my strongest point, but I'll try to keep my focus. I'll be going from the assumption that the talk from the boy is before the talk with Zeke, so that I've got some reference. As far as I know that's possible, right?
Click
I've just tried to pronounced the name like you describe it. I can pull it off one out of three times.
Him being this old my approach had been a bit too childish, but going with the amount of faith in unexplainable things I've observed in these people it could have payed off. It was more of a lightharted joke to open up with, while still being mysterious. And, as player, I could see if the orcs would have been supernaturally gifted.
"No, generally speaking we can't," I told him, "but there are some who claim to be able, some through the Holy Spirit, others through evil spirits. Mostly the latter ones though."
"You know, I don't know how an orange tree looks, but I tell you what I'll do...", I told him, and I ripped a piece of paper from my notebook, and quickly sketched an round shape which I gave a few small dots, I drew a little stem on it and a leaf. (Normally sketching something like this should only take a minute (litteraly a minute if I can't find my shapes well enough).)
"I can give you the fruit of the orange tree, or at least a drawing of it. And you can tell your father that I just want to get to know the orcs. Make friends, and have fun. That and there is a secret that I want to tell you.". I winked at that last statement and pulled up my eyebrows a few times, as to make it lightharted but yet trying to make him curious. I glance over to master Robert once in a while to see how he's reacting to this whole performance. In essance I'm just treating him (Click, not Robert), as a kid.
Zeke
"But Zeke, can your horse make art? Or even appreciate it? You know, I've met this boy called Q... Ql... Click, and he acts just like a regular boy. Curious, interrested, follows his father's orders. He even has abstract thought. He knows about orange trees even before he has seen them and thus, because of the mystery of it, decided that it is his favorite. I don't see a horse do that. Regular animal instinct would normally make them stay away from things they don't know, wouldn't it?"
While I was explaining that, my expression turned to a smile, as I relived the entire scene. But then I turned back to the matter at hand.
"You see Zeke, where I come from we have had something similar. There were people there, humans, as black as coal. We, the white men, thought that they were just animals, if we were thinking kindly about them. Some thought they were demons."
"Yet we were wrong, and we had all the same reasons that you just gave me for opressing these orcs. Right now, where I come from, one of these dark people, well actually a son of mixed parents, is well on it's way to run the country that once opressed them, and he seems to have nothing but good will for it." (I joined the game again before the election of Obama I think)
