When a participant starts asking questions of the group or team, expecting an answer before they continue, or when they start behaving like they are responsible for giving the floor to others, you should react right away. If you let it go on, you will lose control of the process, which is something you are responsible for. It is important that you explain the reasons for your intervention so that everyone understands them and so that you can secure the support of the group. Do so politely and calmly and do not get upset. Take into account the questions that the participant wanted to ask and assess their usefulness and suitability at the given moment. Someone attempting to take over moderation, as challenging as this may seem, is also a sign of their participatory engagement.
