There wasn't anything written about this and I think something was lost in translation. Vice versa, when asked about how much does he talk with Ott, he said "We are good family friends and my son Georg talks with him often. Everything is fine. Ott is also fine."
I tried to understand what could the writer mean by this and the only logical thing would be the leaving of Adamo. Then Oleg Gross said that "Sometimes things happen very suddenly. Adamo's departure was very unexpected."
