The priest did not manage to recognize Cheryl. As a veteran inquisitor, Cheryl's disguise was not botched and clumsy like Teresa.
If the priest was to deliberately spend the time to examine Cheryl, then, his inquisitor's special perception might be able to see through Cheryl's disguise. However, his focus was all on Teresa right now.
Cheryl did not expose herself. Still disguised as a merchant, she brushed past the priest and walked toward the teleportation formation.
The teleportation formation teleports people in intervals. The teleportation formation to Norland will, at most, be able to contain thirty people. There was about a minute or so before the next teleportation.
Cheryl had already passed through the inspections. She was now one of the thirty people that could be teleported next.
She was already standing before the teleportation formation and waiting for it to open to her. Teresa only needed to delay things by a single minute.
