[Cyan springs out of the vent like a spooked animal, scrabbling for purchase on the tile floors for a second. When she gets her bearings again, having been badly startled by the unexpected entrance to her personal space, she shoots back to the vent entrance and yanks it open.]
[When she peers down into it, the vent is empty. She looks confused and frustrated.]
Cyan: "WHAT THE $#@% WAS THAT. How was someone else in the vents?! Do we have a new engineer?? If- if that was an impostor- why didn't I smell blood??"
[Angry and feeling blind-sided, she slams the vent shut again, pulling up Purple's number to send a possible security alert.]
[Cyan has exited the vents.]
