“So, what do you think your blood color would be?” She was so excited, and you couldn’t help but blush, leaning back a little.
“Uh. I dunno. You said that troll’s blood color matched their eyes, right...? So blue, I guess.” You shrug, and watch as she writes it all down. She’s already wearing her entire troll get up, and you really can’t deny that she’s adorable as all hell in it. You know she’s insecure about her appearance, but honestly? She’s just as beautiful either way.
“What about horns? What shape do you think they would be?” How did she even come up with these things, anyways?
“I have no clue. What do you think?” She seems to look at you curiously for a few seconds before speaking again.
“I think they’d come forward, and kinda curl up, like this.” She gestures with her hands to show you just how she means and you nod.
“Sure, that sounds like a plan.” If it made Calliope happy, you were happy too.
“Awesome! So, do you wanna start making all your stuff? You can borrow my paint if you want.” You blink, surprised.
“Already? That was fast. But okay, I don’t see why not.” The way her eyes light up made your entire day.
