I need a researcher chap 10

The contrast between behaviour of students and Jake was huge. While students had all the good manners as Na'vi understood them, Jake knew bloody nothing about it. That was probably the reason why the Na'vi talked more with the students. And the students spoke Na'vi language fluently, which made the children understand them.
'You Dreamwalkers aren't so different' one child said. 'That one has more fingers and...'
'That is because we made these later and by ourselves. So our Dreamwalker bodies are closer to your bodies' Kasia explained.
'Can I touch?' another child asked. Kasia giggled.
'Of course you can. I tried to make my clothes like yours, but I need some help... I couldn't copy them properly without seeing you...'
'Your hair is beautiful' a little Na'vi girl played with Ania's braids. 'I like it.'
Ania guessed that the girl liked the hand-made ribbons she had in her hair. She reached to her bag and took more of these.
'Here, this one is for you' she said, handing one ribbon to the girl. When other kids gathered around her, she gladly offered them all the ribbons.
'Ku'ba' Tsu'tey said, coming up to the students. Kuba stood up and bowed his head.
'Tsu'tey' he said, 'I see you.'
'And I see you' Tsu'tey gave him a carnivorous smile. 'The eight of you, come with me. I'll show you something.'
The Poles stood up and followed the warrior. He leaded them somewhere to the river, and then up the flow. And suddenly they saw a huge waterfall.
'Ja pierdolę...' they all whispered. (A/N: Poles express amazement or delight by this, but it's untranslatable)
'Tsu;tey, why you brought us here?' Kasia asked. Tsu'tey smiled again, showing his sharp, long fangs and causing her to shiver.
'You came for this' he explained. 'You said you came to admire.'
'Then this is a wonderful place for us' Kuba admitted. Kasia patted his shoulder and whispered something in polish to him. Kuba nodded.
'Tsu'tey, in thank for showing us this, we want to give you something special' he said. 'I mean our group hug. You would be the first stranger who received it. Would you accept?'
Kind smile on Tsu'tey's face was enough for an answer. Kasia and Kuba, who were like leaders for the whole group, stood closest to Tsu'tey and hugged him very tightly. The rest hugged the three insiders. Tsu'tey could feel the strong bond among them all and was really pleased he was let inside.
