"Ha-ha, that's very kind of you to do." She drones with a sarcastic undertone. "Do you even realise what you've done and are doing in this room?"

Widowmaker stifles a scoff. "Oh, I'm here for much more than that, cherie, Overwatch will be losing their scout tonight."
Both smirk, an unusual eagerness consuming them.
