Okay, this has been bugging me for a while now...(question/comment about Season 2 Comic-Con Trailer)

The scene in سوال is when "Elena" says: "Katherine's in this house - that means that she's been invited in...what are we gonna do?".
The part that I'm questioning is her voice...
Is it just me that it sounds a little different? Not just mentally (i.e. meaner, colder, fake - although it kind of sounds like that too, a bit), but also physically; anyone else hear a really light lisp? Well, maybe not a lisp, but it does sound different (at least to me)...I'm not saying that it's not Nina Dobrev, because, duh, it is - I just think Nina's talking differently for a different character: Katherine.

So tell me...have I gone insane یا did someone else notice that too? Leave your thoughts below!
