Sometime in the past (I'm thinking before 1900) the gang had to go undercover for a really long time for some reason. During this time one of the guys made too good of an impression on the people they are trying to fool and during the mission he has to avoid getting married to their marks daughter without jeopardizing their mission. He also really wants to get some quality time with the love of his life who is both amused and a bit bothered by the situation. Turns out dodging a betrothal while completing the mission and sneaking kisses from the man you love is very hard work.
