The canon part was that she was angry at her dad for accusing Batgirl killing her brother (again), and they reconciled in Joker #1
Yeah she mentioned in the final arc of Burnside that she regretted didn't take Library Science, so immediately after that she's taking it, huh? But then she travels through Asia before coming back to Burnside.
Oh that's it then, but I thought she quit the congress job because she's being pulled in all direction between Bat fam, Justice League, being accused by her father, her relationship with Bard and her job.
She quits Bard.
if she quits the congress job might as well back as a librarian, although Year One Babs didn't like it and feels she's stuck there.
if they're following the comics, then at least 4 years later. There's still Dark Victory the year after Long Halloween, then Robin Year One, then Teen Titans Year One.
