As much as I appreciate the work done on the “become a Dyad” line I just don’t like that idea narratively. For me, the fact that they are a Dyad from the start explains so much about their connection even before they met. I don’t want to beleaguer the point so I guess I’ll just leave it at that…
Saying “we’ve become a dyad” ends the possibility of always having been a dyad. Saying “we are a dyad” leaves it open to interpretation in either direction… they could have always been one or recently become one. For me, becoming a dyad in the force is more interesting because it means that perhaps Snoke inadvertently made Rey and Ren uber powerful by facilitating the bridging of their minds. I like the change and it’s done seamlessly here. What starts off as a strong connection can become a dyad given the right environment.
