That Zuri wanted the turtle's help was not so surprising. She had once tried to recruit the turtle, when the Inn was much smaller in size. Her pitch back then was that she could provide a much larger gardening space for the turtle than the Inn.
Now that the Inn had grown into its own realm entirely, that was no longer feasible. More importantly, Zuri had quite a bit of confidence in herself. Even back then, she dared to try and poach from the Innkeeper, with the excuse that she knew that the amiable personality of the Innkeeper meant he would not take offense to anything she did in an upright and fair manner.
Now, although she was not poaching from the Innkeeper, the shady way in which she arranged this meeting with Lex left him feeling like she was being spied on. Moreover, she was even meeting him within the Midnight Inn.
