Pretty sure amelia is working for the evil conspiracy terrorists so probably not seeing as they have the queen on their side.
She isn't working for them, she's just a blabbermouth with blind sense of justice and prejudice against nobles that the Daegaz guy simply spill a few useless secrets to make her think he's a someone she can use/will cooperate with her.
After which he just need to wait for her to come blabber all her findings while playing along.
That's basically how Aisha (and Sharon here) got off'd, Amelie heard about Scarlet's false accusation then likely go straight to feed that to very people behind it.
Honestly if we're talking cliche, I can see 3 possibilities for her:
1. Daegaz decide time for subtlety is over, and she get killed as part of the reveal. Maybe with a sarcastic 'thanks for being such an easy to use fool' for extra kick.
2. She accidentally reveal the spy through her mocking blabbering towards Constance (the weird eye thing) thus making her useful for once.
3. She and Constance's friend become 'best friends/rivals'
I don't get how Miriam is smart enough to know Debbie is there trying to cook against them but still lets a girl escort Debbie all by herself. How could you not have foreseen that Debbie would try to cook whenever she was alone with one of the girls? Unless of course this is Abigail cooking instead and it was a trap for Debbie. But that sounds too contrived right now. We'll see.
She believe, and was correct, that Deborah trying to use the girl to dig at Abigail wouldn't work.
Alas unlike Miriam this girl doesn't put Abigail on the altar above all else so Deborah just dig at another, more vulnerable topic (Aldy) and immediately push once she find something, before the girl can calm down and think things through.
