"My Mother is a Pediatric Surgeon"
Well known for being the new kid on the block, Finn's mother is a pediatric surgeon. As such, she performed a c-section on herself to give birth to him, which had unexpected side effects. This also qualifies him to diagnose people with diseases and ailments, such as ulsors. He apparently has some sort of Wolverine-level healing factor, given that just five minutes after his tendons tearing from his ligaments he was able to sprint across the circle twice. He is very passionate about getting others to play Magic: The Gathering (you probably haven't heard of it) with him. He has a birthday party coming up, and would very much appreciate if people would go. His mother, the world renown pediatric surgeon, will be attending.
