Re: Winter Soldier: Bionic arm or not?
There's definitely a lot of material that they could explore with the fact that Bucky is the Winter Soldier. They go go from themes/topics:
1. Steve is no longer alone any more in terms of being the only person from his time who's still in his prime and currently alive.
2. While Steve was slumbering within the ice, Bucky was leading a life where he was being manipulated into being the ultimate weapon for whoever was pulling his strings; how Steve and Bucky's paths in life took such a big and different turn from each other.
