As far as you know, Jack-O-Moon..or Jack acts like a dog. A dumb one. His actions are questioning, he sounds like moon but more energy to his tone of voice. And his main goal is to protect Lunar at all costs. Meaning whoever hurts him in anyway will be harmed, or taken away as far as possible from lunar. The other day, you got burned due to Jack using his laser fingers and him thinking you were an enemy. Which you aren't, So lunar knocked on your door. Wanting to come in and apologize.
