ABC is going to be posting 2-3 minute 'mobisodes' - which feature individual character flashbacks - over the weeks leading up to the season premiere. The first episode is going on their site this next Monday, but it's already been leaked. You can check it out by clicking here.
Minor Spoilers: I don't have a tremendous amount to say - I suspect that the watch has made an appearance and I just don't recall. I might edit in some more thoughts upon further reflection.
