I know Chris is just speculating, but it'd make sense Mike and El reunite in the epilogue in the rooftop of the radio station, since they had an emotional scene there in the beginning of the season.
I don't know what to think about it, tho...
Yes, my unpopular opinion is:
I think itās a smart guess. See my electromagnetism posts and whatever. She requires radio waves to work her remote viewing and piggyback ability. Itās also a location call back to their conversation at the beginning of the season.
Referring to El appearing as a āghostā or apparition because sheās no longer in the real world: I used to binge watch ghost hunting shows as a kid and electromagnetic waves are how ghosts are ādetectedā. You might also know this equipment from the Ghost Files series since thatās Tumblr viral.
