“17. Were they connected to the previous comments, the last one of which was made on21 May 2010 ? I conclude that, although those comments were linked to each other (they were an exchange between Dean Watkins and another individual and responded, on the claimant’s case, to the claimant’s grievance) they do not involve the same individuals as those made from31 March 2010 to21 May 2010 . The subject matter is different and there was a break of nearly seven weeks between them and the last group of comments.”
