Has there even been an official comment on how Leia can sense Luke at the end of ESB even though it wasn’t planned for them to be related at that juncture? Because that’s usually brought up when someone mentions that.
He was specifically calling out to her. One doesn’t necessarily need to be telepathic to receive the broadcasts of a telepath.
All he said was “Leia…Hear me…Leia”
and then she knows instantly where he is. Sounds like Force Sensitivity to me
