Cap attempts to move further up the plane, to help him disarm the bomb… but suddenly, he feels the plane begin to slide out from under his grip. “I’m losing my grip! Bucky! Let go!”
Then the plane slips completely from Cap’s grip. He falls away from the plane, watching the man who has become like his brother these last four years pull further and further away.
And then all he can see is a fiery explosion of white before the water takes him.
