I think they are just screwing with us now. Watching the puppets dance, so to speak.
But speculation is fun! They're giving us something to discuss. At this point, I'm just having fun with all the theories.
People have talked about possible foreshadowing when they showed Danny's ring covered in blood. Instead of it being Lindsay, I wonder if it will be Danny. He almost got himself killed in this episode and with the spoiler about trouble with the Nazi guy I could see him being the one. I don't think TPTB would decide to off the character but maybe Carmine decided to move on. I still really hope it's Lindsay, though.
I agree that after last night, it's possible that they're foreshadowing Danny's death due to his reckless behavior. After all, Danny getting himself killed with all the risks he takes certainly wouldn't be out of character at all.
Of course, there's always the possibility that Danny's recklessness could get someone else killed--namely his new wife.
Again...more angst for Danny, and we all love Danny drama.
My only hesitancy in looking at Danny as a real viable option is that I can't see the show writing out their most interesting dramatic character. And I really don't see Carmine wanting to leave--he's not dumb. This is a good gig for him.
So that brings me back to Danny's oh-so-expendable wife. If marrying Lindsay and having a child on the way doesn't change Danny's reckless behavior, might becoming a single father--literally the only caretaker for his child--be enough to do it? I think so.
I also think there's a good chance the blood on Danny's ring is symbolic foreshadowing.
Those are just my thoughts after this episode. If the Greek storyline wasn't wrapping up in the episode before the finale, I might be a little more worried about Angell. I'm not at this point, though I still think she's an option.
