Parvati arched an eyebrow as she looked at him. "You miss the slight Slytherin tendencies hidden under all this Gryffindor red." She shook her head before saying, "But since it's you, I suppose I will stick to my Gryffindor honour. No one need discover your secret." Ever since she started working with her partner, she'd noted those few things hidden under the surface. This was probably one of the few times she ever joked about it outside of work. "Sounds like a very important sort of gathering. Passwords and all."
Not talking about certain things was something Parvati understood, except that she tended to be a very emotionally driven person. So she wasn't exactly the best at hiding everything away. She just covered it with humour. The laugh made her expression brighten and she went to give him a hug, ignoring personal bubbles. "But Denniiiisss..." Pouting slightly, Parvati looked up at him, making a point to look extra sad.
