ER: son of a Loki

Loki, Prince of Asgard, Odenson, rightful king of Gottenheim, God of harm.I hereby pledge to you my undying faithfulness.

Loki Loveson was the biological son of Laufey, king of Frost Giants, who was abandoned and left to die shortly after his birth. Found by Odin, Loki was taken to Asgard and raised by him and Freija as the Asgardian prince, along with Thor, becoming the Asgardian god of harm.

But after Asgard, Loki took Tesseract from Odin's Vault and in the wake of Asgard's destruction, he chose to stay by his brother's side and support his ascension to the throne. The consequences of his deal with Thanos will soon come back to haunt Loki, as the mad giant intercepted and ordered the Asgardian lions as they made their way towards Earth. In the ensuing chaos, Luki tried to kill Thanos but ultimately failed. When Loki mocked Thanos by telling him he would never be a god, the mad giant cut his throat, eventually killing the god of harm.

So how will close people react after learning that Loki has a son on earth?
