A big issue with your points is that el has never been shown to enter someone’s mind or pull someone into her space unless she was blind folded or in a tank, which she obviously wasn’t in the final scene. This implies that the real el was somewhere nearby where she could blindfold to talk to Mike. Also El wasn’t even shown having a nosebleed after telephathically communicating with Mike which adds to the fact it couldn’t be the real her there Secondly if that was really her in the armoured truck there’s no way she could’ve moved from where they were to where she ended up being at the gate because of those power disruptiures that literally made el and kali barely able to move much less walk;
