Nathan was mentioned several times in Tomoki’s interview. It seems there are 3 parts of interview. The person translated and posted part one.

06:23, when asked about friends of his age, he mentioned Camden and Andrew Torgshev, and then stated that he talked to Nathan and Vincent a lot.
11: 34 when asked “what do you guys talk to each other?” He answered that “normally, it it Nathan, Mariah, Romain and him talking together.” Nathan usually talks about college. Nathan also asks their opinions on what he plans to do, schoolwork etc useful and meaningful stuff. Nathan is like a big brother figure,” a lot mature than the rest of us. He is calm and level-headed. It is like, now that is an adult”
16:43 He talked about Nathan said that he used to both skating and hockey.
20:24, he talked about there are always people like Nathan and Vincent around him, “always one step, two steps, a hundred steps ahead of me”.
24:05 Tomoki talked about terrified seeing Nathan got injured in the gala when attempting a quad toe. He said “ Nathan kept looking at him”. He said Nathan was taken away in a car and it was all commotion. He knew at that time he was going to the junior worlds.
Iirc, Tomoki said Nathan is a very humorous person during some sessions in The Ice Show. I couldn’t find that tweet.
