Flurry: Are you alright back there Starfire?
Starfire: Fine! Completely fine Flurry! Why do you ask?
Flurry: I known you long enough to know when you are nervous, Starfire.
Starfire: I'm perfectly fine! Nothing wrong here what so ever!
Flurry: Are you staring at my flank?
Starfire: Absolutely not! Well… ok, maybe a little… heh.
Flurry: Here's my bedroom, quickly Starfire! Come inside and relax before my mother sees you… um…
Starfire: NOT HELPING FLURRY!!!

Phrasing is important in these situations Flurry, especially if your mother or father is potentially around the corner eavesdropping on your conversation. Considering you two are in the Crystal Palace, heading towards Flurry's bedroom, alone, should excite a lot more caution.
