wouldn't it be interesting if (spoilers)
...Grace turns out to be the real killer, and the men in her life are just trying to protect her? Jonathan ran to draw suspicion to himself, Henry hid the murder weapon, and dad is putting up the money for everything, of course.
On a serious note, I tried to imagine myself talking to a lawyer if I were in her [supposed] situation, and her behavior in that scene with Haley (ep 5) struck me as unnaturally reticent. (And what's with the constant standing up to look out the window?..) I would have been way more accommodating and forthcoming with the information.
My other thought was that Elena is actually alive somewhere, since they did say that the corpse was unrecognizable, and no one ever seemed to mention that they actually confirmed it was her with DNA or fingerprints or whatnot.
