Lots of storylines from EJ's shooting

I don't know how much of what I want to say is spoilers, so I'll post it here. 

How interesting is this investigation/cover up of EJ's shooting going to be?!  I am excited.  First you have Rafe, who is so honest I don't know how he's going to lie or what plausible story he'll come up with for quitting the FBI.  Then there's Will, who apparently saw Sami leave the Manse with a gun in hand.  He hates EJ and doesn't want his mom to get in trouble, so I'm sure he'll side with her and understand why she did it.  And of course Kate, who hates Sami, but probably won't blow the whistle about their conversation for two reasons.  1) If she turns in Sami, she's turning against Will and 2) She knows if Stefano finds out she warned Sami and set it in motion, who knows what he'll do to her!

I guess Arianna is also going to find out and then get run over by a car before she can tell anyone.  That begs the question, who would run her down?  DaysCafe makes it sound like it's not an accident.

When EJ wakes up, he won't remember what happened, but I wonder what all he will remember about his non-wedding day and what his persona will be, good or evil?  Will he be remorseful for what he did or out for revenge for what happened to him?  

I can already see the scene, though.  Rafe & Sami's wedding: either the DiMeras take a shot at her or she is dragged to jail in wedding dress and handcuffs.  Who wants to bet?
