- Epileptic Trees: Her son at the end of the series is Tim's due to his black hair. Heck, some even speculate it might be Damian's!
- Steph mom's mentioned that a girl with superpowers and a guy calling himself 'Dr. Mid-Nite' saved her life from Black Mercy. It's a well-known running joke in fandom that Tim resembles Dr. Midnite's in his new Red Robin costume (Steph even calls him out on it in canon). So... was 'Dr. Mid-Nite' actually Tim instead, saving her life discreetly, or was it actually Doctor Mid-Nite himself? Given Supergirl's superspeed, she could have gotten to either one of them, but given Steph and Tim's relationship, and the fact neither Kara or Steph have ever really interacted with the real doc, its a good chance it was Tim.
- Fanon Discontinuity: The ending in the final, 24th issue practically encourages this treatment for the following reboot Batgirl series featuring Barbara as Batgirl.
"It's only the end if you want it to be."
- Harsher in Hindsight: A letter from the editor in one of the early issues says that, following the announcement of a new Batgirl title for 2009, DC may have stoked rumors that Barbara was somehow going to become Batgirl again, but they never really gave it serious thought since Babs was way more interesting as Oracle, and they'd rather use someone new. Two years later... On top of that, when Steph "died", she said that she was part of the Robin legacy and no one could ever take that away. Well, apparently, DC is "nobody".
- Replacement Scrappy: While this largely faded over time, her replacing Cass was not well-received at first, since Cass had already ate it due to Adam Beechen royally screwing up her character. The sole good thing to come from that was that Bruce Wayne adopted her... Then apparently died in Final Crisis, and Cass was Put on a Bus. While Stephanie is popular among Cassandra Cain fans, the way she was replaced did not endear her to many of Cass' fans (it was eventually retconned that Cass was told to give up the Batgirl identity), especially due to the fact that DC replaced one of the few Asian superheroes with their own ongoing with a White, blonde, blue-eyed successor.
- Win the Crowd: Started off strong and kept going from there. The trades are still often bought at stores and fans were itching for Steph to return and overjoyed when she did.
- Much like the lauded Batwoman material by Greg Rucka and JH Williams III from the same period of Batman books, the series is also receiving a new set of trades, only shortly after DC began reprinting the much, much older Robin, Nightwing, and Birds of Prey series. Demand for the series eight years on seems to be high.
