Cassius knew how it felt to finally have the freedom to do what you wanted when you wanted.

"Right." He said with a nod. "I believe I told you that simply because you can doesn't mean you should, so I'll lay off that now." He stood and adjusted his shirt and coat. "Thank you for your help. Hopefully that will cover the cost of the potion and perhaps you can give whatever's left to the shop owner downstairs for the light I broke." He shrugged. She might keep the money for herself instead. It didn't bother Cassius either way.
