Ava took a small step backwards, shaking her head and gritting her teeth.
"You're right," she said. "Clearly, you're making very grown-up decisions. You're not a kid." When it came to drugs versus cigarettes, she figured it was the same either way, and if either of them kept it up they'd die early deaths.

"Clearly you don't realize that if I don't use this, they'll be able to kill me easier." he told her, crossing his arms. "I'm not fast enough. I need to be faster. And until I can find a more permanent solution, this'll have to do."

Shaking her head but smiling now, Ava put her hands up again, this time in surrender.
"You're right, you're right," she said with a small laugh. "Take care of yourself, alright?"

"Yeah, you too." he replied. "Keep in touch, alright? If something happens, I'd like to know. And thanks."

"Don't sweat it," Ava said, waving Ed off. "See ya around." With that, she turned and walked away, disappearing around the corner of the alleyway and vanishing into the cold air.
