"Mm', yeah. If the person themselves is unavailable, which it sounds like they are."

Taking his palm off his cheek, Oliver reaches forward for the grocery bag, and dumps it out onto the coffee table. There's a piece of chalk, a few gemstomes, and several chunks of iron.

"Tracking magical signatures is hard to demonstrate without doing it," Not that it's stopping him any. The gems and iron get shoved over to the side, before Oliver starts using the chalk to draw a circle. Draws several overlapping circles inside the first circle. "so I can just do it, and if you guys decide to fuck me over and not pay me back the IOU, I'll just curse you." His tone is nonchalant; whether or not he really means it is something else entirely. Revenge takes effort, and an owed favor is likely not worth it.
