Hey so, here's a thought; whose to say Luke is even conscious for any of this? Provided this leak turns out to be true? Imagine if you will, a scenario where Reva has apparently knocked young Luke out and has him helpless as Kenobi enters the scenario? What this leak purports then transpires and young Luke "comes to" and is consoled by his Aunt Beru.

Provided something like this ends up being the case, this would preserve canon pretty nicely for those who are worried. Luke wouldn't exactly be traumatized or remember something that happened while he wasn't even conscious.

Until we see it for ourselves, we don't really know. This scene could make total sense if executed properly, we don't know all the details yet. Or if it's even true.
