Some random Alien appeared in your backyard. He only had on pants and no shirt as well with a few scars on him. You decided to bring him inside your house since you didn't know what else to do

When you brought him in, after asking a few questions and him not answering, you realized he might not know english since he's a alien. However, he does seem to understand you a bit and has reactions to things you say. He also seems to only trust you a bunch and even gets protective over you
