I've noticed a few people who have mentioned the episode where the nurse asked for Carmen Lee?  Well, I've just thought, that what if, yes, she was asking for Carmen Lee, but she actually meant it spelt differently.  Carmine Lee.  Why is this important?  Carmine is a shade of red!  I'm not joking, look it up!  Carmine is a deep red colour.. Like the colour of blood!

Could this be some kind of clue?

It may not be important but I just thought I'd mention it anyway!
