Sai thought he might have heard voices in the next hall over and paused just long enough to see if they sounded threatening. He looked back at Shikamaru, wondering if he'd heard them too. Chances were it was just another couple patients, but they couldn't assume too much. They'd make their way quickly through this hall and hopefully avoid any trouble.
"Down this way," he pointed one pale finger toward the first of two halls ahead. "There are doors at the end that lead outside." It would be simpler if the greenhouse had been directly connected to the main building, but this wasn't the case. The other ninja would already be aware of all this due to previous trips there during the day, but a reminder couldn't hurt - especially since things tended to look different after dark.
