I would have been annoyed and confused at Colin too because after the tragedy, Colin was friendly and sympathetic toward Jeremy, and as soon as he,Colin, joined the other lot and before Jeremy was even charged, the poison started to set in.
There's a part in Colin's book where he mentions the attitude of the relatives and also that he thought SJones a bully. Then there was the " mistaken phone-call from DB " who thought he was speaking to someone else other than Colin.
