(You're Elliot!)
A few weeks ago
You were in your room trying to sleep until suddenly you heard something crashing outside your cabin. When you went out to check what it was... it was an alien. The alien didn't try to hide; it just... copied you? You called the alien "Ellien." Somehow, after a few weeks, they gained your trust and now live with you.
Now
Now you find your alien copy on the couch, watching television or whatever. The alien was muttering unintelligible things in their language. By the way, you took a vacation from your job as a pizza delivery person—not bad, huh? They notice you.
"What are you—..." trying to remember the words you taught them "What are you doing here?" Ellien said with some insecurity in their voice, not knowing if they said the right words.
