It would be impossible for Luke to conceal the fact that he’s coming from Faust, especially after integrating the EOD universe with the Cosmic Roads Superposition.
Mainly because Luke ends up on State-Zero before he makes it to Solace. that’s in the center of the Tesseract, center mass. time flows much more slowly there in relation to more distant Earth states such as Solace. while telepathic communication is nonlocal, thus bypassing temporal constraints(likely by way of the Tesseract), once Luke has to effectively bare his soul to Sarayu to make it to Solace, it becomes an unalterable event.
The theoretical laws of temporal causality directly apply to the Tesseract on the grounds that it can be used as a kind of time machine – and you can never change events to the point where you didn’t enter it – because you’re already there….
Faust would know he’s coming because Sarayu would be so deep in her telepathic link with Luke – merged with both him and the ship, for all intents and purposes, she’d effectively be in a coma, and when she comes out of it, he has ways of making her talk – and the most effective is depicted in Mongrel – Time War Mix – a Roshani dueling whip – a neural whip that random re-tunes its oscillators to keep the nerves from deadening to the pain. in the wrong hands, it can be lethal…..
