after clair had been pushed and the mcqueens had found her a phone started ringing and they answered it nd leo was on and 1 of them said it was calvin's phone nd then calvin was seen walking up the steps.. so dus that mean it could of been calvin??

personaly i think it doesnt, every single suspect in this will somehow be matched in connection of this sometime or another just to keep it fresh and confusing for others.

Yeah but i think it is too obvious if its Calvin because there is ment to be a twist!
