The Ancient One’s Initial Refusal To Train Strange
This feels like a cheap shot to Doctor Strange, but given that the MCU is a complete body of work, I do have to bring out that it is a weird error that the Ancient One rejected training Stephen Strange immediately. This is thanks to Avengers: Endgame, where Hulk visits The Ancient One long before she meets Strange officially. Because time is relative, however, she knows who Strange is and decides to give Hulk the Time Stone because Doctor Strange “is the greatest” of them. I know Doctor Strange came years before this moment in real life, but considering how carefully crafted the MCU is, someone should’ve remembered that.
