I interpret the quote to mean that Jonathon’s criticism of AG about withholding information has contributed to the breakdown of his relationship with Alex S— given that Alex S likes and respects AG. Of course we know other things contributed to their relationship breakdown like Alex S’s suspicions of Jonathon.What?!!
Alexandra found out something from Glasenberg? She stopped talking to JS in December, 2018 after something happened at Jonathon’s cottage.
