ok, i just watched episode 19, coming from someone that didnt saw the original anime nor played the game(only saw fate/zero) i was a little confused last episode, i even tough that the 2 pendants thing was a translators error or something i didnt understood right!

but now its starting to come all together, loving the little time paradoxes they are throwing there (like the pair of swords that came from nowhere).

now i have a few questions (no spoilers tough as i am enjoying the series a bit too much right now):

is the timeline circular in this story? i mean does the emiya spirit always comes back to fight as rin's champion and gets to see his young self everytime or in the first timeline rin summoned someone else?

i understood that there are 3 different storylines in the game, is archer always emiya's spirit or only in the ubw story?

also in the game do they reveal that archer is emiya himself in the other storylines? or you only get to know that in the third replay?
