In the 2nd season of “Game of Thrones,” Arya Stark (Maisie Williams) has escaped King’s Landing following her father’s execution. Dressed as a boy, she vows to get revenge and ends up in Harrenhal, a castle that houses Tywin Lannister’s army against Robb Stark (Richard Madden). There, Arya becomes Tywin’s cupbearer and uses her position to gain any information she needs about her family and other happenings in Westeros. Her efforts do not go unnoticed by Tywin, who engages in conversation with her.
In a Showbiz CheatSheet article detailing things in the series that don’t make much sense, the outlet highlights that Tywin does not become suspicious of Arya. Servants are not normally well-read, smart, and sharp, nor do they usually have interest in their masters, especially if said master is a Lannister. However, this does not seem to bother Tywin, as he never investigates and learns that his servant is actually the sister of the man he is trying to kill. Tywin should know when he is being manipulated, and though he might not find the Starks to be a threat, he could have easily used Arya as leverage against Robb. Indeed, this would have shown just how vicious and strategic he is, allowing him to stay true to his Lannister name.
