A good number of people know it, yes, so it is useful to learn. And hey, you can always use it with me! When I'm not working, I can totally hang around with you. I love people, and it's been far too long since I've really gone out anywhere. I'll definitely be happy to teach you!
Forensic evidence is stuff left behind at a crime scene. Like when someone gets killed or is kidnapped, I study everything left behind to help find who the person was that did the killing or kidnapping. I basically can find out how the crime happened and who did it. Superman is just one man. He's a superhero, someone that protects people from bad things. I don't know everything in the world, but I can definitely teach you what I know! And don't worry, some people would probably say I'm aggressively nice too, so I think we'll get along!
Let's see, the Apocalypse is basically the end of the world. Demons are bad creatures. They can possess people, so you can't tell what they are except that if a person is possessed, they have completely black eyes. Thus making them a demon. There's an apartment complex that has magical protection around it to keep the bad things out. Do you know where you are right now?
Oh, good! I like talking, it's a side effect of being raised by parents who were deaf. I like making noise whenever possible. I don't like it when it's quiet, it's unnerving. I also talk to myself a lot as a result.
Also, do you like hugs? Because I like hugging people, and it's helpful to know in advance if someone likes hugs or not. I'm not a fan of getting hit or something for hugging someone.
