I recently got a review back from consideration. One review was a little odd in that the reviewer(s?) consistently referred to themselves using "We" and "Our". It seems highly unlikely this is the royal we. Notably, it is just this review, the other reviews all use singular pronouns.
Is it typical for a manuscript review request, which is typically only sent to one individual, be reviewed by multiple people? I am not sure how reasonable it is from an ethical perspective.
