Wow, this is very creepy. It says both me and my alt are in the picture, but really only my alt is there! I was on my alt when I was first there, but then I switched to my main because it had cubimals! Weird!
If you look really closely you can see your mohawk coming from behind jess's head. So my guess is that the ghost of your alt was there for a while after you switched to your main.
