Fleur was certain Killian was somebody he could trust, he was kind of like a big brother figure, considering he's never had any siblings, he was delighted by the idea. An older person, who would look after him... Fleur wanted to do the same to repay his kindness. He listened to the many voices talk and bicker, show their anger, confusion and distrust. But Jehumon had to be telling the truth, Fleur had already pinched himself many times between waking up and drinking the soup, the only reaction being the red marks on his arm.
He placed the now empty stew beside him.

"Je vous beleive Jehumon ! Nous n'avons pas vraiment beaucoup de choix de toute façon ... Mais je tiens à répondre à vos amis dans le villiage digimon" After voicing his concern about the matter. He then realised, he was talking in French and they oribably didn't understand him.
"Uhm.. I beleive... Jehumon... Let's go... To Digimon Villiage!" 
Fleur felt proud that he managed to translate his thoughts to english, even if that wasn't exactly what he said.
