[SPOILER POST] Glee Spoiler speculation: Seven people, Seven theories

Recently a Glee Spoiler has been released after Dianna Agron tweeted this picture with the caption 'at work' and it was confirmed that they were filming a car accident scene

The fact that Dianna tweeted this suggests that she could possibly be involved in the crash or connected to the person who was. So here are my theories of who could be in this crash...

1. Quinn
One of the top candidates considering who tweeted the original photo. This would be an interesting way to wrap up her storyline, whether completely (via death) or by injury. Quite frankly I think killing off Quinn's character would be too sudden and extreme for Glee but Quinn still takes the top spot for most likely victim in the crash
2. Shelby & Beth
Obviously Quinn is heavily connected to Shelby and Beth through Beth's adoption so that would explain her presence. If Shelby died it would be a good plot device for keeping Quinn in Ohio if she chose to stay for Beth. A death would also provide a parallel (since Glee is so fond of those) to Season 2, which also featured a wedding and funeral episode.
3. Artie
If Glee went the flashback route this could always be a flashback to Artie's accident, possibly brought up while Quinn is driving Artie to Regionals rather than his dad this season. It would explain Quinn's presence and there has been talk of a Quinn/Artie relationship going somewhere in the past. Of course this is also possible without Quinn if she is not involved in the accident at all and were being thrown for a loop.
4. Rory
A possibly obvious candidate if the powers of Glee have decided to give Damian a quick exit
5. Santana
One of the most unlikely and far fetched candidates but possible. Santana's always talked about living on 'the wrong side of the tracks', would that be the city or rural? If it was rural Ohio it would explain why she was driving in that area.
6. Cooper Anderson
As the episode this scene is being shot for is assumed to be 'Big Brother', the episode where Blaine's brother Cooper Anderson is being introduced, it could very well be him. We haven't been told which side of the crash Quinn would be on (if she is) she could have been the one responsible for the crash if she hit Cooper.
7. Burt Hummel
a drive to Washington gone wrong? Another unlikely candidate since Burt has been victim to a near death incident on Glee already and both Burt & Mike O Mallay are much loved members of the Glee verse but still plausible. It would also again bring up the question of who is going to run the tire shop which I've been wanting addressed again.

Some of these are completely unrelated to Quinn but the trick of a actor having nothing to do with he scene being on set, or tweeting photos for someone else, has been done before.
