He starts being interviewed about how he solved his mental issues, maybe by a doctor or family member.
that's not true, he is asked what i think is a very obvious question, how did he climb this mountain which he seemingly just climbed in 2 seconds. that question seemed to be the most important and relevant question at that time in the video. there are other questions, but that seemed especially relevant because it is about something very large that just happened moments ago. (also another added twist is how did someone ask this via postal mail so quickly)
