It took him him only five minutes to realize she was uncomfortable as well. The movie was ignored in favor of watching her from the corners of his eyes. He only moved back into his seat slightly, mentally cursing himself for not acting more appropriately. It wasn't her fault she hadn't understood - the language barrier, obviously. Lingo or euphemisms wouldn't be available to her after all.
He only moved slightly away from her during the movie, covering it with a slight stretch, as his eyes remained ahead. All in all, he was quite happy to have it end and he stood as eagerly as she did.
"It was better than I thought," Luther said, moving to step out. Immediately he knew his leg was going to give him trouble, though he disguised the wince. He made a note to take Katya's opposite arm once they hit the street - it would do a better job of hiding it for now. The last thing he needed was further awkwardness, when he'd already made her uncomfortable.
