I have a question about Bedivere. If I remember correctly, Artoria (saber)'s excalibur was returned to the lake so she was able to pass away peacefully. The Bedivere that we summoned has the Nuasa arm. He should not have the arm if he was Saber's Bedivere, so I thought that he is similar to Emiya (assasin) that came from an IF timeline. However, Mashu said at the end of the chapter that, if they can summon Bedivere, he would not have any memory that they have met before (the whole Camelot things).
This makes me confused--which one is the Bedivere we summoned?.
Saber's Bedivere should not have Nuasa arm. On the other hand, if it was chapter 6's Bedivere, wouldn't he go like "why the hell do I have this arm with me O_O?", based on what Mashu said about him not remembering them.
Then again, if he is indeed Bedivere from chap 6, why would he forget about Mashu since everything he did in that chapter was while he was a human?
