I just can't wait for the big Ep VIII reveal that Rey is a Palpatine and it blows everyones minds
The context clues are all there:
-British accent (dumb i know, but in SW this denotes senatorial/imperial lineage)
-utilization of Juyo stabs similar to Palps in ROTS
-the disembodied voice saying "Kill him" in her head after defeating Ren, in the novelization (Palpatine's order to Anakin in regards to Dooku's fate in ROTS)
-lastly, the look in Luke's eyes when he sees her, showing not just reluctance to train her now, but a knowing look of failure and reluctance to train her in the past, likely out of fear.
