Romilda grinned at Zach's compliment, and leaned over to give him a kiss on the cheek. She hadn't had any of the pumpkin juice yet, she just liked being affectionate with him. It was easy, natural.
Then she settled into eating, and did wash her food down with the juice. Not a lot of it, but not because it was spiked, it just wasn't her way to drink much as she ate. She was much more concentrated on the food.
"Hello!" she said, looking up when a new person entered. "It was a bit of a spontaneous lunch - I brought this for Zach, and Gilbert joined us. There's plenty, if you'd like to join."
Possibly this friend of Gilbert's would do an excellent job in helping them with their plan. He couldn't be too badly off if he had a pretty lady friend, could he?
