*All right, now we have our glorious Key’s teaser images out. Key looks peaceful in the first photo, but the wall in the background looks like a cellar or underground room. Is he locked in there? What is the device that is behind him in the 3rd photo? Is it a torturing device? His green hair color, is there a meaning? The blue smudge on his shoulder in the 2nd photo looks like a bruise, doesn’t it?

Here’s another theory: Minho is a suspect, and Taemin, Onew, and Key are victims. And Jonghyun may appear clothed in a Sherlock costume tomorrow 😉 Let’s see…

According to a fan’s theory: the third photos show what they were like before something bad happened. Taemin’s and Key’s pose in their second photos suggests they are victims. If Onew is also a victim, then why is he smiling in his second photo?

Hmm…my guess (WARNING: this can be creepy and disturbing. If you are pregnant or a minor, please stop here! ;P): Minho, a spoiled rich young man, is a serial killer. He kidnaps, tortures and kills boys. Key is his first victim. His third photo shows him as he is kidnapped and locked in. The green o in Sherlock in his first photo shows he’s been dead. That’s also the meaning of the bug on his mouth. Taemin is the next victim. He is about to eat the poisoned grape and staring back at the killer in his first photo. The second photo shows his fate. Onew is also kidnapped but still doesn’t know what’s happening and is smiling innocently in his second photo yet. His first photo, however, shows his life flickering away (the letters Shirlock blurred). What do you think?
