Batman: Arkham Origins - 10 Coolest Easter Eggs, Secrets And References Explained

7. Doctor Young's Apartment, And Scarecrow's Visit To Blackgate

But of course, Origins doesn't just pay reference to Batman's wider universe - it also includes some sneaky nods to characters that first appeared in Arkham Asylum.

While in Lacey Towers, the player can actually find the apartment of one Doctor Penelope Young. Doctor Young was of course a pivotal character in Batman: Arkham Asylum, and was involved in the manufacturing of Titan before being killed by Joker towards the end of the story's second act. You can't actually go into her apartment in Origins, but it is there, clearly signposted, and with police tape preventing anyone from going in.

Once the player reaches Blackgate, they'll actually be able to find and consult the prison's visitor log. One of the most frequent guests is none other than Doctor Jonathan Crane, aka the Scarecrow. One would presume he was up to his usual tricks in the prison before Arkham Asylum was reopened, but obviously not as his alter ego.

One other nod to a future Arkham character occurs while the player is in the Batcave. On one occasion, Alfred will inform Batman that his friend, Tommy Elliott, had called asking Bruce to celebrate after a successful surgery involving twins. There has been some speculation that the twins in question are none other than the Abramovici Twins from Arkham City, but that remains unconfirmed.
