Pan Jun
Despite his failure to assassinate Lü Yi, Pan Jun did not stop speaking up about Lü Yi's wicked deeds every time he had an opportunity to meet Sun Quan. Over time, Lü Yi fell out of Sun Quan's trust and favour, and his abuses of power eventually came to light in 238. Sun Quan removed him from office, ordered Gu Yong to thoroughly investigate his crimes, and had him executed. After the Lü Yi scandal was over, Sun Quan sent an apology to all his senior officials for not heeding their advice and urging them to point out his mistakes.
