Mikaela moved slightly so she was facing him when he showed her his arm. She looked at it in awe. She was nerding out so much at that moment she couldn't ever describe it. Even she could feel Wheelie was curious about it, as he was leaning against her to watch the arm closely.
She looked at him for permision to touch it before she'd put her hands on it. But she really wanted to touch it. And play with it, see how it worked. "It might be old, but it's definitely effective," she said as she looked at it. "I'd love to know how you can control it without being attached to you... It probably has some sort of sensor or chip attached to your brain, and that's why you can control it," she murmured. She looked up at him when he mentioned what he wanted to add to his arm. "Claws, uh? Not trusting security around here, I see," she chuckled.
