I actually think her parents will be less inclined to help than we're speculating. Bear with me a moment,
If we look at what she does; false flags, secret cameras, manipulating human assets, setting up patsies, multiple identities, crime to fund ops etc. then it reads like the intelligence service playbook, but like it was written in crayon. These aren't the actions of someone that's being groomed by incredibly experienced intel ops, this is the behaviour of someone that's bitter that her parents have done some cool (depending on your context) shit and feels like she needs to prove that she can be just as cool. That's some serious insecurity there. Like she's reaching 'really' hard to try and scream 'I don't care that I'm the disappointment in the family'.
Although, obviously her parents are going to perform damage control, but I suspect that's more to preserve their own reputations, which (again depending on your context), they worked exceedingly hard for. I think protecting Bella will just be a byproduct of them not wanting to get dragged down. But I honestly think that whatever we say about her here, nothing is going to be as difficult for her as having to look those parents in the eye and explain how her stupidity and complete ineptitude put everything they worked for at risk (well, not really at risk, but it's certainly an embarrassing stain), as well as having to explain some pretty awkward shit that would be awkward shit even if it didn't come out from the world's worst 'my first opsec' playset.
