... I might reveal it to GM so they can weave it into the storyline ...
As much as you want. Obviously the more we know the more we can bring it into the story. The other players have a role in that too, so share with them too when you feel it appropriate.
PbP stories take a long time to unfold, so 'waiting till later for a reveal' can often run into the problems of never getting there, or the big reveal falling flat, and that is assuming we don't run into the standard 'secret' problem of those events never coming into play at all because --not knowing better-- the story went in another direction.
Push for that story and we will trust that apparently-strange beats are due to things we don't yet know.

... I'm going to leave Cat's involvement with the conspiracy a mystery ...
Cool. Can you tell us anything about the conspiracy and what happened, or is all we need to know that 'there is a civil war'? We don't need to know how you were involved
or how it was your fault.
Drop me a Note with what I need for your story, but also tell the other players as much as you care to about your part in things, so they can bring up those events from their own perspective.
Example note, you should be able to click on it to 'reply' in kind.

... as far as the other characters, they can think whatever they like ...
You can also tell us what your character has told our characters, and we can try to keep those in-character reactions appropriate to that.
WhtKnt says:
... does not really explain her urgent need to leave ...
Presumably some of the others trust you, so that should be no problem for them. There are a lot of people leaving in a hurry.
WhtKnt says:
... She took a crash course in Astrogation ...
I am sure that 'go-getter attitude' impressed whoever was bringing the crew together --presumably
Raf. And that past friendships added to the Skills you could bring.
WhtKnt says:
... does not hide her Social Standing ... will verify her status ...
Can you tell us --possibly when it comes up in play-- about these verification processes? Is there a standard system, or is it different depending on who you are verifying for? Else I can make something up, when it comes up.
