It hadn't occurred to Arialla that her dolphin's form might resemble a shark well enough to bother Henry -- and, having dipped into the waves, she didn't see his reaction.
As she returned, she let out a loud "Ecch!" when her transformation led to her holding the mucky, algae-covered object in her mouth. It hadn't bothered her in her dolphin form, but as a human? Truly disgusting. Quickly, she spat it out into her hand, then washed out her mouth with sea water.
"I found something shiny," she said finally, walking up out of the waves, "but I'll need to clean it up to tell what it is. How about you?"
Looking at Henry, she noted his work and smiled. "Seems like you've been having a good time here. I think those will look really nice on the firling."
