9. What has Thea been up to?

The younger Queen isn’t seen in the premiere, but Guggenheim hinted that episode two will provide a lot of answers. “As we were breaking this episode out, we discovered, ‘It could be more interesting if Thea, who left town at the end of season two, wasn’t around.’ And it’s part of the mystery,” he said. “Where is she? She’s not in Starling City. … You’ll find out where Thea went.” And just what was said in the limo between Thea and Malcolm? That will also be answered sooner rather than later. “The beginning of episode three is [where] we pick up with Malcolm and Thea in that limo and we hear that conversation that you didn’t get to hear at the end of season two,” Guggenheim teased.
