Dezire makes it back to the obligator's chambers without event. The guard movements are like clockwork, and she's already snuck around them once this evening.
Around this time, Mateo sits back in the chair and sighs heavily. While his search has turned up some documents that will make his work the following day more efficient, he failed to turn up the journal they were searching for. His eyelids feel heavy and the weight of a day of travel, and a tiring search of the office, begin to wear on him. Knowing he'll have plenty of time to continue his search the next day, he leaves the office and returns to his chamber. There he finds Dezire, waiting to share with him news of what she found in the basement.
I think it's fair to use the same check - nothing has changed yet, the commotion hasn't drawn attention ... yet. Mateo, you're back in the game!
