Basically just Rayla being curious on how to draw and Callum's like: well heck finally something I'm good at for god damn once lemme show you.)

Timeline; somewhere after season 3)

Callum sat down on the edge of the rushing stream. He closed his eyes for a moment and took a long, deep, peaceful breath. The scene was amazing. The air was warm and it carried the scent of the fresh water. Aaaand the tranquility of the moment was destroyed by Rayla landing beside him with a loud thump. Callum yelped in shock and flinched back, before realising it was only the elf. "Gosh... where did you come out of?" He asked, settling back into his position with a small huff. "You should watch your surroundings." Rayla teased, leaning against her blades and looking down at him. "If I'd been an actual enemy, you'd be pretty dead." Callum rolled his eyes, opening his sketchbook. "I suppose. But Xadia is so peaceful right now. I highly doubt anything dangerous is around." Rayla eyed him skeptically. "Uhh, Callum, let me tell you something. Xadia is probably the most dangerous place of all of the kingdoms." She picked up a small beetle. "Little, but deadly. If this little thing bites you, you will get a nasty sickness that gives you hallucinations." She threw it into the bushes. "Xadia may be pretty and all, but dangerous. We have to keep an eye out." Callum shrugged. "I guess. But how bad can it get?" Rayla sat down beside him. "Pretty bad. Whatcha drawin'?" Callum looked at his messy sketch of the river beside him. "I don't even know." Rayla looked at him, then back to his drawing. "That's pretty good if you ask me." She commented. Callum shrugged again and closed the book. "Not really. It's a quick sketch with not much put into it." Rayla laid back with her arms splayed out. "I would be glad if I could draw at least something. The best I got was a sketch of...." she trailed off. Callum perked up slightly. "Of what? Do you have it with you?" He asked excitedly. Rayla looked away. "Of my dad..."Callum hesitated, then took his hand in hers. "I'm sorry..." Rayla shrugged. "It wasn't that good though. I threw it away afterward." Callum's eyes widened. "But why? Every art peace is beautiful in its own way!" Rayla let out a giggle. "Trust me. If you'd have seen this, you would have had a heart attack." Callum's eyes widened more, and they sparkled with a new idea. "Can I teach you??" He asked pleadingly, giving her his adorable stupid human smile. She didn't want to disappoint him, but she also didn't want to make a fool of herself. "Ugh, why not. Show me your stupid human ways." He forced her back into a sitting position and handed her his book eagerly. "Okay, try and draw something." Rayla gave him a irritable look. "Do I have to?" "You agreed." He said, smiling teasingly.
