YMMV / Arrow S 5 E 16 Checkmate

• I Knew It!: Many fans had called it that Talia was the woman in Russia who trained Prometheus (because there wasn't any other women in Russia who Oliver knew). But many were surprised that she deliberately trained him to get revenge on Oliver, many assumed that she hated her dad just as much as her sister did.
• It Was His Sled: If you knew anything about the character (or watched Legends of Tomorrow), then you knew Talia to be Ra's al Ghul's daughter from day one.
