The New Commander-in-Chief?

"Your Imperial Majesty, it is the reason why we are pulling you out of the Winter Palace. As you are the Empress of the nation, you are the one responsible for giving the Emperor an heir. But given that he doesn't have a male heir yet means his responsibility now falls to you." 

"Sergei…what are you implying?" Sophie said, almost stammering as her heart still beats in a rapid worried state. 

"It means Your Imperial Majesty, His Majesty, Alexander Romanoff is incapacitated given that we cannot find or contact him. Due to that, we are enacting the continuity of the government. His Majesty's executive power will now be transferred to you until further notice…" Sergei explained in a way she can understand the responsibility that she had gotten just now.
