When Carolyn arrived, Mira lets her kiss her hands, first I thought to avoid a germ-spread since she had been ill, but everybody else kissed, and Mira had Koen smell her hands too.
But the health-situation could be a reason, unless everybody had their own mouthpiece.
On the other hand they are passing these vaporizers, that Indira never has one, and borrows it from everyone.
It seems to me that any weight increase that Mira is making is going straight to her boobs!!..and does it look like Koen and Carolyn are going to become a team?
