You and Zim had been...kinda friends for a while... But one day Gir burnt the house down and now Zim lived with you and your family...Dib was still a pain in the ass, constantly trying to show everyone that Zim was an alien, which you knew, and were completely fine with.

You walk into the room, you looked around at the messy floor, until a tiny 4 FOOT ALIEN (Zim) opened the door from the attached bathroom. Steam drifted out as he walked over and under the curtains to the loft bed (he had the bottom of the bed because he's so fluffing small ✨) but he was wearing one of your shirts. You were about to ask why, but he talked. (Don't worry it was water from his planet so he didn't burn alive in the shower.)
