It is being rumored that the character of Isabel Rochev (Summer Glau) may be Slade's daughter Rose Wilson in Arrow, according to a recent report.

Which Characters Will Die By Season 2's Shocking Finale? 

In an April 14 interview with TVLine, the producer of the CW show, Andrew Kreisberg, spoke about certain theories surrounding her.

Rochev came to the fore in the last episode of the show as she betrayed her business partner Oliver and took over Queen Consolidated, which also got fans wondering about her origin and backstory. Kreisberg suggested that there could be two possibilities. Either she was Slade's daughter Rose Wilson or Robert Queen's former mistress.

Thea to Stop Oliver from Killing Slade in Episode 19?  

"There are always two ways to go," Kreisberg said. "But you will get a lot more about her backstory and her motivations in the next episode."

Here's the official synopsis for the next episode, The Man Under the Hood:

Oliver and Felicity Join Forces to Take Slade Down in Episode 19?   

"Deathstroke Hits Oliver at Home - Oliver (Stephen Amell), Canary (Caity Lotz), Diggle (David Ramsey) and Felicity (Emily Bett Rickards) return to the lair and find Slade (Manu Bennett) waiting for them. An epic battle breaks out and one member of Team Arrow is sent to the hospital. Thea (Willa Holland) hits her breaking point, but just as Oliver is about to reach her, Slade intervenes and Oliver is faced with a choice - his battle with Slade or his family. Meanwhile, Laurel (Katie Cassidy) struggles with a new secret. Jesse Warn directed the episode with story by Greg Berlanti & Geoff Johns and teleplay by Andrew Kreisberg & Keto Shimizu."

Arrow will return on April 16 and air at 8 p.m. on CW.
