I will skip all considerations on Riley being now totally corrupt, since it has been said already. I have really a hard time buying a part of the dialog between Tar, Burt and Riley. "How do you know her?". Really? I can overlook that Kalani actually mentionned Lizzy in his log, Riley might have forgotten that. But the question is just... how did he knew her? I don't know, maybe the months and months and months she spent with the Mallers? Am I missing something obvious?
