Faraday isn’t Eloise’s son
Her behavior is odd. No real mother would be so driven to push her son into a situation where she kills him.
But they would if it was part of plan to protect her son. What if she tried to plug in a different variable. Someone else raised her son (like Aaron) and she took on a substitute son (like Ben’s Alex); her real son being someone abt. Daniel’s age (and in play on/with the island). A son she would push into physics over music and kill in the future/past, while her real son is ‘safe’.
