After her initial contact with Croix, Terezi went about to do what she was planning to do: going straight for the Sheriff's Office, of course. She's going about as fast she can, with a mental note on how much more difficult it's become to breathe. All the while, she was thinking about that message--sure if they were able to find them all and turn them on that would be good. But she was also mentally preparing herself for the possibility of some kind of malicious sabotage.

That aside, she made quick use of her time and was entering the office as soon as possible. She will be checking every possible nook and cranny for something out of place.
