Like, the one we summon is the Lostbelt Morgan or the PHH one? Because she has voice lines from both versions, she knows what happen in the LB and she also antagonizes Artoria(saber).
Spoiler Alert: Kinda both. The Morgan from Faerie Britain has memories and knowledge from Proper Human History. That's why she knows what happen in both world, but the body is comes from Faerie Britain. This will explained at the main story.
