This is just hard to watch. Imagining Miku, after coming down from the manic episode from losing her mind, just completely shuts down when hit with the ever looming presence of reality, and becomes emotionally unstable, completely co-dependent, and is ultimately an empty shell.
And Teto, practically worn down by the same mesmerizer subjection, is the only one who can support her.
So, then what level is the Tarnished, considering they beat Radahn and then also the only person to stalemate him?
By the time the Tarnished fights him, he's been severely weakened by the Scarlet Rot so his level would've been way lower during that fight. Malenia was equal to him in strength when they fought, and her level was definitely higher than his when she unleashed the Scarlet Rot.
