She probably saw him wandering the halls looking a little too at home. Suspicious and all that stuff (maybe climbing into a vent or two).

Also, she might know that he's a lying sack of shit who told Steve he was going to some nice college on the East Coast and definitely not Avenger's Academy, just ask Nat, she can vouch for me. And then proceeding to go to Nat to presumably pack for the Quinjet later in the week. Ahaha.
