Bruh ain’t no way this man about to pull a Sigmund Freud on the ml

I dont understand the joke. Whats pulling a Sigmund Freud?

It a meme about Sigmund Freud theory that children unconsciously, in a repressed way, wish to have a sexual relationship with their parent of the opposite sex - boys with their mothers, girls with their fathers. It’s all joke of course
And here I think that the marquess is going to use that red hair girl (who look suspiciously similar to ml mother) to seduce ml lol

Thx for answering my question.
