Is there any mistake in the plot: the school principal calls Sophia twice and they talk about the same thing twice? Did Ava then hear Sophia's phone call and on the pretext of a double paycheck, tell her to come on Saturday to tell her? Sophia only said that the boys had to take the condoms off, but she doesn't tell them if they should throw them away. Isn't that just another copy of working with veterans when he bought her a sexy outfit and Sophia should come in sexy outfits for the boys to see her?
