'Arrow' season 2 has has fan favorite genre star Summer Glau on an unusual track as DC villainess Isabel Rochev, keeping the character out of play for long stretches of the season, before finally making some major moves against Oliver in the recent episodes. Last night's "The Man Under the Hood" introduced a few more startling shifts for Glau's character, but what new DC alias will Isabel Rochev take in the coming weeks, and how differently had producers planned the 'Firefly' star's role for the season originally?

You're warned of spoilers for 'Arrow''s most recent episode, and potentially even episodes beyond, but may fans were less than surprised to find that Diggle's shooting Isabel Rochev during the climax of last night's "Man Under the Hood," didn't exactly take, considering Glau has notably been photographed on set in an outfit somewhat evocative of Slade's Deathstroke getup. Producers have confirmed that Glau's now MIrakuru-enhanced Rochev will take the identity of DC's Ravager, though not as Slade's daughter Rose Wilson, as in the comics.

That said, it seems writers had initially envisioned a vastly different trajectory for both Rochev and Caity Lotz's Sara Lance, as at one point Sara was to begin the season as Ravager, rather than assume the Canary identity. Even then, producers weren't quite sure what to do with the Rochev character during the season, as Andrew Kriesberg told TVGuide:

Isabel was the one thing we weren't entirely sure about as we were developing the season. Truthfully, there was a very early iteration of the series where Sara [Caity Lotz] started the season as Ravager, and then we switched over.

Part of the reason Isabel disappeared for a while is because we still weren't quite sure which way to go, whether she should be an ally or a villain. We had written it so that it could turn out either way. The scene that I was picturing was Isabel, Slade and Sebastian [Kevin Alejandro] in Oliver's office, the triumvirate of evil. Once that happened, there was no way she was not going to be Ravager.

No word yet on when we'll see Summer Glau's Isabel Rochev in her proper "Ravager" debut, but in the meantime, what do you think? Does Rochev's twisted history with the Queen family make her an effective second villain for the end of the season? Will she and Slade manage to drop any bodies from Oliver's team before the finale?
