Isaa and Lais already knew Kendra's mind. They choose to show Isaa's little space as Lais her own. So when they rest they won't notice the strangeness.
Kendra told them, after Marcus left, about that idea and it was acceptable. After all, Kendra planned anyway to make one small space for Lais. She smiled at her and remembered the stuff Marcus left her.
It's fine if her space doesn't grow further for now as long they had some save heaven. She gave a wink and a big smile at Lais and shook her head while pointing at Isaa. Tassio and Lais understood her idea. Lais' face was filled with excitement while Celia looked at their expressions, not understanding what is going on.
"Tonight." That was the only thing Kendra said and winked at them. Isaa, Tassio and Lais nodded.
