is this love? ODD PART!!!

[everlastingRAINBOW]

So I'm watching the is this love? PV for the first time and I noticed something odd, I'm sure some of you had notcied this too but I wanted to put it up for discussion!!!

When she walks by her bed you see her and then it gets foggy:


Then I notice something flop off her bed...:

AN ARM!!!!!!

I was just like whoa.... Why is there someones arm!?!? You can see the fingers and everything! Here are three possible reasons...:
#1. She was having a 1 night stand with a guy and used her evil physic exploding powers to killl him!
#2. that's her...
#3. that's the guy she wasn't sure she loved, so she killed him (with her physic powers of course) and thats why at the end of the vid she smiles!

I really doubt these reasons, lol, but I can't think of anything better! Does anyone have any ideas?
