The Australia job that they'd thought would be a breeze, turned out not to be one bad piece of luck after another. Half the team got food poisoning one day from bad seafood. The chemist got a bad batch of somacin that turned their trial run into an actual nightmare complete with zombies (she blamed Eames who'd been up watching "28 Days Later" the night before). And then there was the actual day of the extraction. Ari kept watch as they went under with the Mark. Things seemed to be going fine as far as she could tell and with 10 seconds left on the clock she prepared for the team to wake up and to up the dose on the Mark so he would stay asleep. Which was exactly what happened. The Extractor had gotten the info and they all packed up and headed to debrief in the warehouse before they would go their separate ways. Which is when, of course, she missed a stair as they went down the stairwell of the Mark's apartment building and sprained her ankle.
