Mia Sutton's arrival didn't catch anyone's attention; in other words, no one even noticed her.
Firstly, because Jensen Sterling upgraded his room, differing from where the rest of the film crew stayed, they naturally didn't encounter him. Secondly, Mia usually didn't go out, and when she did, she was always fully disguised. With so many celebrities in the hotel, no one would notice her.
The rest of Amanda Summers' crew had already left, and Mia mentioned she had some matters to attend to, so she stayed behind.
The film crew had a relatively simple shoot today, and the process went smoothly. The leading actors were in great form, so filming wrapped up quickly.
Another reason could be that Zach Sheffield, who was inserted into the crew, unexpectedly showed significant improvement in his acting recently, making it watchable, hence speeding up the progress.
However...everyone watched as Jensen had removed his makeup and was getting ready to leave.
