[She gives him a flat look and then recites the following:]

There are five known exits out of here, and an additional three outside. The person who is the greatest threat in this room is unknown, but the greatest known one is standing next to me. Rin and Shirou are there and there. [She points to the both of them, easily picking them out of the crowd.] Since I can summon Excalibur and my armor at a moment's notice I am never unarmed. Potential ways enemies can come is by either as dance attendees, or bursting in through the windows, or simply walking into the doors. If such a thing happens, the chaperones are capable of managing an evacuation and defending the students, which I will happily assist in.

[She turns to Archer with her free hand on her hip and a flat look.]

Archer, I have had to switch between being a courteous host to a fierce warrior in the blink of an eye before. Please do not insult me by implying I ever stop being a knight. That is the very core of my being and you have no right to decide if I am acting appropriately or not for a knight simply because I am trying something new.

[Oddly enough, the dress being short she had no issue with. No, what she takes issue with is how tight the bodice is.]
