Consort Jing's crime of erecting a memorial plaque for Consort Chen was actually a request by the Emperor. Nevertheless, to keep the fact hidden, he punishes Consort Jing lightly and quickly returns to his palace to listen to Xia Jiang, Prince Yu, and Prince Jing. After countless arguments, Xia Jiang requests to interrogate Mei Changsu for the case, much to Prince Jing's displeasure. After knowing Xiao Xin is a spy, Consort Jing offers to let her go, with a condition that she reveal the whole setup to Prince Jing. (Source: Wikipedia)
