Redd found this new person interesting. He was similar to a goblin, but Redd didn't think he was a goblin, or at least not exactly goblin. He did not quite have the words to state how was related, nor the context to give those words any meaning. While he had only seen goblins other than possibly this one person, or what he presumes is all goblins, he had some understanding that there was more than rocks and goblins. 

A thought nagged at the back of his mind, he didn't look like a goblin, maybe his blood tasted differently than goblins, and maybe different goblins blood tasted differently, however looking around, the most appeasing "doner" was the big guy. Surely he had enough blood to share a bit of it. However, he didn't know if he could simply ask. What if he was greedy and did not want to share. 

Redd began to hug the wall of the cave, and tried to sneaky move towards the two older creatures. However, he failed miserably. Firstly, he was red, and that didn't help him blend into the stone wall. Secondly, he was not very good on his feet. About half-way to the two figures, he tripped over a rock.
