Raph always knew there was something fishy with you, you randomly showed up and you became best friends with his brothers, even Donnie!

One day he pulled you aside from his brothers and attempted to talk to you "Alright, buddy. What are you?" he asked, getting straight to the point, poking at you.

He made sure to stay quiet enough so his brothers didn't hear since he didn't want to make them upset by his gut instincts.
