SPOILER WARNING: This article contains major spoilers for "Second Chances," the latest episode of "Arrow."
Tina Boland has a secret, and that secret is her true name. In "Second Chances," the latest episode of "Arrow," Team Arrow learned that Tina was an undercover cop who was affected by the particle accelerator explosion, which gave her the gift of a sonic scream. As it turns out, "Tina Boland" is her undercover name; her real name is Dinah Drake.
If that sounds familiar, that's because Dinah Drake is the name of the original Black Canary. Dinah debuted in 1947's "Flash Comics" #86 as Black Canary. Later, she married a man named Larry Lance and subsequently changed her name to Dinah Lance. Inspired by Dinah, her daughter Dinah Laurel Lance would go on to become a founding member of the Justice League. When the New 52 restarted DC Comics' continuity, the Black Canary legacy was retconned, and Dinah Drake was restored as the one and only Black Canary. This New 52 version of Dinah Drake was formerly married to Kurt Lance, but the two divorced.
As such, "Arrow" is honoring Black Canary in a way that even Oliver Queen can't recognize. The name Dinah pays homage to Black Canary's long history at DC Comics. It's also worth nothing that, in "Arrow," Laurel Lance's full name is Dinah Laurel Lance; further, she is named after her mother Dinah, but her mother was never a masked vigilante and Laurel came into the Black Canary moniker very late in life. It could hardly be more fitting, then, that Tina's true name is Dinah.
In "Second Chances," Dinah proved to be difficult to recruit. Stubborn and violent, she refused Team Arrow's help until she had no other options. Though Oliver advised her not to, she murdered her lover's killer in cold blood; after ruminating on her actions and the emptiness she continues to feel in the wake of her lover's loss, she ultimately accepted Oliver's offer to join Team Arrow and revealed that "Tina Boland" was only her undercover name.
Dinah also triggered another mini-crossover event in "Arrow." After all, Dinah was originally a member of the Central City Police Department, which is where "The Flash's" Barry Allen works. Oliver called Captain Singh as Green Arrow in order to learn more about Tina's work with the department, only for Singh to scoff at his claim that he was truly the Green Arrow. Oliver quickly texted Barry to give Singh a sign that he was who he said he was, and Barry zipped into Singh's office and left a note on his desktop that read, "He's legit."
