Cass knew that they were going for a full show, but he didn't realise how big of a show until they were at the edge of entrance to the temple. Not quite near the front doors, not quite away from the front doors, Cass was aware that it was probably a priest's hallway to allow for movement around the temple away from citizens prying eyes.
They could hear how many people were on the other side of the rather thick looking wooden door, and that alone made Cass realise that while they had gotten the news late, no one else had. These slimy fuckers. Cass could tell that Vespertine was pissed about this, as was Lady Ava, though her anger was far less obvious.
