Was that Denzel in the body bag?
I've seen the movie several times now, and one thing I'm still trying to figure out is the scene when Denzel shows up at the scene of the first ferry bombing. He's standing near a row of body bags containing some of the recovered victims and his phone rings. Then, as he goes to answer it, he looks down at one of the body bags and seems to react as if there is a phone ringing inside the body bag as well.
I took this as a clue that the body inside the bag was the version of Denzel from a prior failed attempt to go back and prevent the bombing... and that his same phone was on his body inside the bag. My friend, however, disagrees...
What's the opinion of others? Was that another version of Denzel inside the body bag, or am I reading too far into this?
