Spoiler:

Allthough this is just my speculation, but in the manga the Earl says there was a betraying Noah. And I think about her personality, she seems to rather not know much about the world. So In the end I think that Lumiere or what her name was is not gonna kill Allen and them. But later on gets killed by Tyki while nearing the Asia arc.

Spoiler for reply to Ztrik's speculation:

Spoiler for minor(?) spoiler to the plot:

Spoiler for still not recommended to proceed...:

But the Noah that betrayed him was killed several (hundred) years ago.

... And Knowing the Noahs though, despite everything, they're still a very close family.
