Frank got that scorpion just to tempt Gerard. He knows, okay? But that's alright, because he's pretty sure that Gerard is deliberately taunting him when he writes on himself with Sharpie or eyeliner, thick black letters gracing the cords of his neck or the soft, pale flesh of his inner arm, daring Frank to trace them. Frank thinks it's maybe a good thing that Gerard has issues with needles: if he actually had permanent ink there, Frank wouldn't be able to restrain himself.
