The fake Joker was Sae's cognitive version of Joker, kinda like Haru in Okumura's palace(the one you fight in the bossfight). So basically the fake was just a version in Sae's mind, not the real one in any way. (Idk if you figure it out later in the ep, i'm way to early for that)
Haven't fully watched the video yet, but to explain, Akechi isn't Dlc, he was in the base game, but in royal his social link was added, so this plays out just like in the base game
Bro really got the bad ending 💀 You should probably just reload your save instead of starting the new game, cuz 1 it takes so long to get there again. And 2, You can just go for the good choice, since there is a lot more stuff to discover
To get the answers of the other people, you have to activate the network settings/the thieves guild, this will also allow the public executions which can get you some really good moves on personas. Great episode again and already waiting for the next one.
Little tip for the different confidants, on the rail map, you can look at which confidants are free at the moment and who you can rank up with. I dont know the keybinds for pc tho so you will have to figure it out yourself:( ps: really focus on maruki, his abilities are really good for combat and his storyline is also cool
