YES her PB is Ming-Na Wen! And yeah, I've seen some of AoS! Ofc since it's a PB deal, she doesn't look exactly like Melinda May -- the haut are genetically designed to be preternaturally beautiful (through several centuries of genomic refinement). Not that Ming-Na Wen isn't already a babe, but the haut consider themselves works of art just as much as anything else they do, and the haut are very Extra. Haut women also never cut her hair, so Lady Diya's hair is EXTREMELY long, but she tends to wear it up so it doesn't get in the way.

THAT SAID, feel free to have her remind Nat of May -- it's just not quite that level of face twin-ery.

And yes, Diya definitely is a puzzle here, and by all means try to decontruct her, Nat :B
