Emilia is definitely Satella [discussion]

Remember the 3rd trial Emilia was shown in the sanctuary what if that future has actually happened what if Satella comes from the future where that event occurred causing Subaru to die we already know that Satella has the power to control time and space thanks to the return by death Subaru has so I don’t think this is too far fetched as we have already been shown that Emilia can easily from her friends deaths so imagine to what lengths she’d go to if Subaru the one she loves were to permanently die.
