Harry had woken up earlier. Chalking it up to a night on the bender, much like he had in his youth, he wasn't as concerned about waking up on a bench in a station as he should have been. What he was concerned about, however, was his missing pocket watch that Mrs. Weasley had given him on his seventeenth birthday.
He was speaking with the attendant, who wouldn't let him speak really, and trying to tell him that he didn't have any luggage, but he was missing his watch. Of course, the conversation was going nowhere, and there were suitcases and trunks with his name on them.
"Listen, have you got a floo? I need to firecall my wife, she's probably wondering where I am."
Of course, he didn't account for the fact that his wife was here with him, in this strange place, but when he saw a young adult woman with Ginny's red hair, he looked up.
"Gin?" He yelled out to the woman. "Ginny!" Of course, if it wasn't Ginny, he'd be incredibly embarrassed for shouting out in a public place.
