"I can soulcast better than you." he said to Shallan.
"Oh, is that so? Lets see what you can do, then." She said, mocking.
Smiling, he closed his eyes and let his mind slip between the realms. When he opened them again, he was standing upon a sea of glass beads, with the cold sun shinning distantly in the black sky of Shadesmar. Bending down, he thrust his hand into the rolling beads and found the one he was looking after some probing.
"Would you like to become something new?" he asked, holding the bead to his eye. The bead gave a faint tug, trying to hold into its Identity, but it finally gave in, changing from a deep blue to magneta. He closed his eyes and slipped back into the physical realm, almost effortlessly. He was getting good at this. He reopened his eyes to find Shallan still watching him with a self-satisfied smirk on her face.
"Gave up al-" she started to say, but he wasn't looking at her. Or, rather, he was looking down past her neck with a wide grin on his face. Uncertain and a fair bit annoyed, she looked down herself.
"Aaaaiiieeeee!" she screamed, with good reason, for instead of her blue havah, she was clad only in a strange set of small-clothes. A wide ribbon-like piece of pink cloth which did a poor job of covering her breasts and put her cleavage on wide display, and a very small pink loincloth which barely covered her privates and left her butt bare.
"See? I turned you beautiful! Now that's some serious soulcasting, I might say." His grin widened and he winked at Shallan, who had by then turned a bright red, which made her freckles even more pronounced.
"FIX THIS RIGHT NOW!" She shrieked at him, but he only laughed and shook his head.
"Tsk tsk, you are in no state to be ordering me around. Besides, I ran out of stormlight."
In a jolly tone, he continued "You'll have to walk back to the camp, Miss Radiant."
