Be sure not to “wrong” the person but to steer their contribution towards a time when their questions, comments or input can be channeled into the process. Ask them to hold their thought/question/idea until the group gets to a phase where this kind of contribution fits it and is constructive. Keep in mind: not the comment itself is wrong, just its timing. If necessary, highlight the idea that rounds support everyone’s opportunity to be heard and to listen.
