Have a lot of Talia headcanons
• Talia sneaking into her father's library and pouring over his medical texts trying to understand. Her father finds her asleep there most nights, sometimes he just quietly carries her to bed; other times he wakes her up and answers her questions in serious scholarly fashion, telling her complex medical details until she falls asleep in his arms.
• Talia begins assisting with healing and field medicine at 12. By the time she's 17, she's sat in on multiple surgeries. She has the steadiest hand in the League.
• For my League worldbuilding, I rewrote the Year of Blood from being a year of mindless atrocities to the Year of Blood and Honey, a quest meant to teach the value of both life and death replicating the journeys of Ra's Al Ghul before he founded the League. One of the parts of the quest is taking a dragon bat like Damian's Goliath, which means in my AU Talia has a dragon bat named Akila.
• Talia makes her first serious escape attempt at 14. She packs a bag and saddles Akila. It takes her father's men three weeks to track her down. After that, her father talks to her about duty and responsibility, and tells her that when she's a little older she will be allowed to leave to pursue her studies. Talia throws herself into preparing for medical school.
• At age 6, Talia sneaks into the classes for the League's incoming cohorts along with the other children of League members and watches them train. She learns a lot just by watching. This is how she actually meets Bruce Wayne, although he doesn't remember her well enough to distinguish her from the other children and has completely forgotten their earlier meeting when they meet as adults. He gives her little bits of chocolate, and she tells her friends that when she grows up she's going to marry him. Talia does remember this, but she's a little embarrassed by it and she's relieved that he doesn't seem to connect the dots.
• When Talia is about 11, there's a harassment situation involving her and one of the trainees. The League has a no tolerance policy for harassment and assault - you have to be able to trust your brothers and sisters in arms absolutely - and usually mandates that the offender fight a duel with either the offended or a champion of their choosing. If the offender wins, they are merely dismissed from the League's ranks. If the offender wins, they can choose the offended's fate. Talia chooses to fight the duel herself - she wins, and spares the man's life out of compassion, to her father's faint disapproval.
• Talia's most prized possession, next to only her gifts from Melisande, is her med school diploma. She has it on her wall where it's the first thing she sees every morning. She brings it with her when she travels. It's something she earned, something the League didn't give her.
• Talia regularly submits to medical journals. Her father cuts her articles out of them and keeps them in a scrapbook with family photos and other sentimental items.
• The year after Damian is born, there is an attempt at an alliance between Slade Wilson and the League that results in Slade courting Talia. Talia is deeply depressed due to Bruce's absence and her own post-partum depression, so she goes along with it rather mechanically. After the alliance fails, she hides the pregnancy from Slade. The child is abducted by a rogue fanatical sect of the League that is largely unaffiliated with the Al Ghul family and raised as a weapon. This is Respawn's origin in my AU because I find the "Ra's Al Ghul cloned him for spare parts" origin unappealing.
• It's critical to my understanding of the Al Ghuls and the League that both Damian and Talia did have a childhood. They weren't raised as weapons, but as royalty, the heirs presumptive to Nanda Parbat. They had responsibilities and they trained, but it was not a strictly abusive experience for either of them. Ra's Al Ghul is a complicated man, but he loves his daughter and grandson.
• Much of Damian's early upbringing was handled by servants, as Talia suffered from post-partum depression. She visited him often, usually bringing food she'd made herself, but she doesn't feel that she was always able to be the mother he deserved.
• Talia always felt a little set apart from the other children of the League due to her status. She is glad Damian has Mara and the Fist (who in my AU are either children of League members or children who were abandoned by their parents due to metahuman status) because she wants him to feel that distance less acutely than she did.
• Talia and Diana find a lot of common grounds in their upbringing, it's one of the things that draws them together when they meet as Lexcorp CEO and Themysciran ambassador.
• Talia loves Bruce in an idealized way, and she had a largely political affair with Slade, but the bulk of her romantic connections have been with women: Shiva, Jade, Angel Breaker, Diana, arguably Selina
• Talia handpicked Angel Breaker to serve as her bodyguard due to a crush she wasn't ready to acknowledge. She considers Shiva her best friend.
• Talia and Ben Turner have a standing weekly tea time during his tenure with the League. It's one of the few things about that time in his life the Bronze Tiger misses. Talia is one of only two people who know of his son with Carolyn Wu San, the other being Carolyn's sister Shiva.
• Talia sent Damian to Gotham during a League Succession Crisis because she was afraid he'd be used as a pawn if he stayed. She wishes she could've gotten Mara out as well.
