One of the endings I briefly considered for "Secrets and Riddles" is Patricia taking blame for pretty much everything to protect Jacob and Helena (and even Merula). And even though things don't really add up, the Ministry is like: "Well, she insists she's guilty, and we're not gonna argue with Rakepick, alright". So she spends some years in Azkaban, but then there's the big escape of the Death Eaters, and Patricia is like: "Ok, I'm done with it", and so she escapes as well.
Shortly after that, she finds out where Jacob lives. And one late evening, when he's reading, he suddenly hears a knocking at the door. He opens it, and he sees Patricia.
"Hello, Mr Ellis," she says with a sly smirk.
He smiles broadly and says nothing for a while. "You came here because you had nowhere to go, or you just missed me?" he asks eventually.
And then later it turns out that nobody looks for Patricia since there was something sus about this case anyway, so whatever. The war is over! But Jacob and Patricia keep living together in semi-hiding because "we tried the world, good God, it wasn't for us".
And only Helena starts noticing at some point that someone might be watching her. But weirdly enough, it doesn't feel threatening... Almost as if they were just checking if she's fine. So, one day, just before leaving the meeting with her brother, she adds:
"Oh, tell Rakepick I said hi."
