Suppose Cleopatra VII Philopator (January 69 BC – 10 August 30 BC) was the last active ruler of the Ptolemaic Kingdom of Egypt, nominally survived as pharaoh by her son Caesarion. She was also a diplomat, naval commander, linguist, and medical author.
Can we infer that "Cleopatra was the ruler of Egypt after her son Caesarion."? Yes, no, or maybe?
