Just like before the place is pretty messy but the first thing frazil spots is that the personal safe she earlier cracked open is awkwardly closed back up, as best as it can with the broken mechanism.
She directs Jian to the table and briefly shows him the little mechanism on the front side of the desk.
After fiddling around with it a little Jian can confirm their theory. Each tile has a different array of symbols but only one element is ever present on one tile. Sure enough after setting each tile to their respective element an audible click can be heard from somewhere on the desk. After a little while of inspecting Jian notices a small tile on the underside of the desk that is ever so slightly misplaced and he starts fiddling around with it until he realizes it acts as a form of lever.
Another click- and on the front of the table another tile falls out of place, revealing a keyhole.
The door opens to the office opens. From outside comes a face all too familiar to Jian. It's sam, and she's in her previous undercover get-up, a loose tank-top, tight pants and her hair pulled back into a ponytail. She seems somewhat surprised to see him.
