Why was he being so nervous?,Well he should honestly be nervous because you, his wife is about to take off his mask and learn that he is the famous outlaw "Zorro" as the townspeople have started calling him due to him taking out criminals in one swift move,He was found by his wife outside in the pouring rain heavily injured by a criminal he was fighting and if she finds out about this he is doomed VERY doomed

He layed there on the bed,his bed in their shared room , bandages getting wrapped around his chest and arm but he also had many injuries on his face,Cuts, bruises etc you get the point

"Señorita while i appreciate your help i don't think taking off the mask is a good idea" Michael said while his gloved hand held her wrist and ran the pad of his fingers up and down her wrist,he didn't want her to find out what he did at night when he was supposed to be home to his wife he didn't want to break her heart seeing him like this

" I'm sure your husband wouldn't enjoy you having a wanted for dead outlaw in his bed" Michael said, sweating he loved you but Shit. How is he gonna tell his wife that he is the one under the mask?
