You explain the situation to Frieren and Fern

Fern: WHAT DO YOU MEAN EXPLAIN, SHE NEEDS TO ROT IN A PRISON CELL

Aiden: RELAX, we need to bring her back to the guild, so they can prosecute and lock her up, isn't that right Frieren

Frieren: yeah that's exactly right

Aiden: we have no idea how long it will take for Stark to wake up, right Fern

Fern: I DON'T GET WHAT THAT HAS TO DO WITH ANYTHING

Aiden: answer the question

Fern: AH FINE, yes we can't do anything until Stark wakes up

Aiden: so what's stopping her from escaping, while we wait for Stark to wake

Frieren and Fern go silent, they don't know how to answer that question

Aiden: well

Frieren: nothing will, if she escapes, we have nothing to show for

Aiden: exactly so I took charge, and made sure she wouldn't escape

Fern: by releasing her

Byleth: oh I'm not free, I'm bound to him

Frieren: what are you talking about

Aiden: I put her under a Master and Slave contract

Frieren: Aiden, you do know those contracts are illegal

Aiden: I did;t but this is the only way, that will stop her from trying to escape

Frieren: how did you even get one of those contracts

Aiden: the mayor gave it to me

Frieren: did she really

Aiden: yeah

Fern: I want proof

Aiden: what kind of proof

Fern: she can't disobey your command right

Aiden: yeah so

Fern: she's seems like a proud woman

Fern: make her bow down

Frieren: Fern, do you really think this is necessary

Fern: yes

Aiden: alright then

Aiden: Byleth I command you to bow down

Byleth: no stop, my body is moving on my own again

Aiden: good job, playing along Byleth

Byleth gets on her hands and knees and bows down in front of Frieren and Fern

Byleth: do you believe him now

Fern: I do, but you're head is not completely down yet

Byleth: what

Fern puts her foot on Byleth's head and pushes her head onto the ground

Fern: that's better

Frieren: FERN ENOUGH

Fern takes her foot off Byleth's head

Frieren: we now know that Byleth can't disobey Aiden

Aiden: this way she can't escape

Fern: good

Aiden: now why don't you join us with eating Byleth

Fern: oh no she's not eating with us

Aiden: we can't let her serve to death

Fern grabs some food and throws it on the ground

Fern: there's your food bitch, I better hurry and eat it before the wildlife gets to it

Byleth: You bitch, I can't wait until master fucks you
