So this is really more of in general question as opposed to a thought but here I go
As we know there is a huge amount of parallels between Levi and Mikasa.
I've been thinking alot about Kuchel lately mostly did she go to underground on her own or was she potentially also trafficked into it like Mikasa and her mother nearly were?
As Mikasa and her mother were targeted for their racial identity at the time. Given the one rare shot of Kuchel with baby Levi, she was very beautiful.
And like Mikasa's dad Kuchel probably didn't have her Acker abilities awaken either
Is it ever mentioned if she willingly went or was she taken?
Kenny tells Grandpa Ackerman he finally tracked her down.
And she wasn't using their family name (which could have been a thing before she left or was taken)
As she did have another name, her working name Olympia.
I also wonder if whatever happened to Kuchel (leaving or taken) just kind of had serious effect on Kenny and why he's killing Military police, not just cause of every else we know of like Persecuting remaining Ackermans.
