Maybe friends/supporters of PJ? I think PJ is probably extremely jealous of Dan. One of PJ's main functions at LL was to help with filming and editing. He has proved to be pretty poor at both these. He is less skilled and also less popular than Dan is. Dan may not be perfect bit he can turn his hand to practically anything and produce satisfactory or good results. He is prepared to work hard and he is likeable. He has a better personality and sense of humour and can manage to get away with the odd veiled criticism of SJ. PJ will not like any of those things. When Amaury arrived, PJ appeared to like him and probably thought it would be good for him to strike up a friendship with SJ's cousin but Dan gets on so well with Amaury and probably has more in common with him in terms of interests, skills and sense of humour than PJ would have as he lacks those things and is less likeable, so he may despise Dan for striking up the friendship and also be jealous that SJ seems to enjoy mentioning it. In comparison with D and A, PJ is an immature little boy and, underneath, he is aware of that.
