While Bruce and Alfred travel to England, Spain and Greece to find a painting Martha painted, a location in an old picture of the Waynes, and the spot where Thomas proposed, Damian is back in Gotham, starring at the sun until it goes down, so he can dawn the suit, and fight some serious crime.
Lord knows, Damian has fun doing it, Bat voice and all. The threat at hand involves some guy who has been stealing gas, and blah blah, who cares about that, because god damn it, Damian is dressed up like Batman and it's awesome!
After dealing with the forgettable gas thief in his last night as Batman, Damian flies back to England to meet his father, who is already waiting for him, having known Damian really never left, citing some less than impressive green screen technique. Nevertheless, Bruce couldn't be happier or more grateful for Damian and all the thought he put into the trip. The two end their vacation of sorts watching Alfred act in a play with an old flame of his... As they wait for Alfred after the show, they soon find him storming out, insulted by the woman who gave him stage notes during the play. Basically Alfred says "Fuck England, let's get out of this shitty country and never return." Well alright, Alfred!
