Just like a date 

"What are you going outside for?" Grand Lady looked at Luci and Evan with an intimidating look. She seemed to feel that her power was at stake here, even though neither of the two youths in front of her wanted to challenge her power.

Evan glanced at Luci, as did Luci who was now like a chick on the edge against a predator. "We just want to go for a walk, Grandma." That was the reason given by Luci.

"Go for a walk? Where?" As Evan had predicted, Grand Lady asked for more details about their itinerary which was actually to meet with Spider to discuss the hiding of Bruto.

Again, Luci just seemed to frown, even though she maintained her mentality. 'Calm down, Lu! You already discussed this with Mr. Evan earlier, right? Now calm down! Your unnatural behavior will make Grand Lady even more suspicious of you,' the girl thought incessantly.
