Seems like Nico has finally gotten Unforgettable, but I believe it won't be like his abilty in the previous loop that made him go insane.
I believe this abilty of Unforgettable will allow to keep his memories he had before he got the abilty, having no risk of losing them with every new thing he learns.
I suspect this beacuse he is holding onto Apocalypse which holds a ton of memorys of all the previous loops, yet he still able to rember his happy memories with Ichico.
just realized one of the artifacts Apocalypse was going to reveal the location of in ep16 is Remember, which is funny bc... it's right there. In Andy's head. Wonder what Juiz was thinking at that moment lmao
