Tamlin and Azriel were arguing, Azriel was so tired of him, so when he began yelling at him, he just shut up, rather uncharacteristic of him, Tamlin spat words like venom, and Reverie was sick of it, seeing that Azriel was at least a little affected by Tamlin's words, she couldn't bite her tongue anymore. She was always the one to win the argument, so when Tamlin called him a bastard, it was the drop that filled the glass for Reverie
