Well wasn't this entire encounter one surprise after the other. Jake couldn't see well enough to know exactly what was wrong with her dress, but he was sincerely hoping this time it wasn't his fault. If it was a malfunction of some kind, the only thing he could do was offer her his coat and help her get to one of the less-public spaces.

"Here, take this," He said as he swung off his jacket and held it out to her. It would look likely just as suspicious as whatever was wrong with her dress, but better than exposing herself somehow at the very least. "I believe the retiring rooms are this way." He gestured, forgetting they could scarcely seen one another. "Behind you." He tried again, rolling his eyes at himself and hoping she definitely couldn't see that.
