So she's been an Erwin stan from the beginning, right, like he's the only one whose name she actually remembers. And we've just reached the choosing Armin or Erwin episode. Here's a little best of of her comments during the whole ordeal:
"Ah! I knew Erwin was going to show up!" "Of course they're gonna turn him into a titan." "It's so obvious he's a titan shifter already, that's why he told Levi to give it to Armin!!!!"
Boy oh boy will she be disappointed once she realizes he ain't gonna come back
