Yeah I really like the flashbacks. Mostly because they are progressing Oliver's backstory. Each builds of the previous one and does not just rehash the same stuff. I have been wondering if towards the end of his time on the island he is alone. Maybe for months or even a year or longer. In the later bearded Oliver footage he seems completely alone, surviving by himself. I hope we learn that is the case. It would fit with the comics and it would show how he built himself up to the level he was when he was discovered.
