That's why he hopped out of bed the next morning to take the camera out for a very specific purpose. After explaining to Emily's mother Olivia that he forgot something, she went up, snatched the camera, and then went downstairs.
He did this because after using the camera so much and experimenting with so many different people, Rick got obsessed with that feeling, the feeling of being someone else.
Once the camera was in his hands, he knew he just could not start taking pictures as he pleased because Emily would notice, so the first thing he needed to do was turn off Emily's awareness, which thanks to their previous use of the Camera, was not very hard to do.
"Ok, Rick..." Said Rick to himself after making sure only the user of the Camera was aware. "It's no biggie, it's just going to be a little time. I take a pic of myself, I stay as whoever I ends up for a while, and then I go back to normal. Easy." Said Rick excitedly as he prepared the Camera to take a picture of himself. "I guess it's time to say cheese!" And with that, Rick took a picture of himself, watching the flash of the camera activate. Now the question is, who did Rick become?
