Ashe smiled at Griz quite apparent fear, it would make sense. He was afraid of her genius or maybe because, as he said, of the explosion. Not that it mattered for her, she needed both for her experiment and wouldn't take no for an answer. 
She put a hand on the goblin's shoulder and with a calming voice, similar to how her human mother would sooth her when she had a nightmare said : 

"[Color=silver] I understand that you might be afraid. I am too, for not being afraid of the unknown or something that can cause you death, would mean you were stupid and you ain't. I've heard quite a few stories about you, brave hunter and warrior of the tribe. You won't need to do anything more than watch. I need your expert eyes and ears. [/Color]"

When hearing Breden's words, she scoffed. "[I]Directly hit by it[/I]". Not very smart. Why would she try to do that? She could've tested the potion directly in the village if it was like that and with a tone as if to teach a child, she said : 

"[Color=silver] Breden, Breden. I could've done that in the village if I wanted, wouldn't have I?
No, what I need you to do is to simply light the fuse at the end of it and use your young muscles to throw it as far as you can in a clearing of trees. After that I will calculate, using Griz's expertise how far the splinters flew, what direction and other similar stuff. It's just a test.
Also, I need some ingredients. Plants. I used a lot in making that test sample and if I works as intended, I will need to make a new one to show the chief.

She didn't mention the fact that the plants would be bothersome for her to carry alone and the help of two goblins would make the task easier and safer.
