"Welcome back, Eliza," said Tom. "I hope you've enjoyed your holiday in Taiwan?"
"Well, thanks for asking. It was going perfectly until you ruined it," replied Eliza whilst rolling her eyes.
"There are plenty of time to fly to Taiwan again after your mission," answered Tom. "In compensation for ruining your holiday, the headquarters have decided to buy you another ticket to send you back to Taiwan after you've finished your mission. But this time, you're going by First Class!"
"OMG! Really?" exclaimed Eliza in ecstasy as she dashed forwards to hug her boss. "Thanks, you're the best boss ever, Tom!"
"Right, enough chit chat," said Tom as he quickly turned around to hide his blushes. "Let's get down to business. Your mission this time is to investigate on a Maths teacher at Playmobil High School."
"OMG! That's the high school we've attended!" interrupted Claire in astonishment.
"Yes, exactly. That's why you two are the perfect candidates for accomplishing this mission," responded Tom. "As I was saying, a teacher of mathematics at Playmobil High School, whose name has escaped my memory.....ah yes! Ms. Verinder..... Her conduct is extremely suspicious as her students have performed extraordinarily well in the previous year's examinations."
"What's so suspicious about that?" questioned Eliza. "The students could've simply worked their arse off for that exam!"
"Yes, Eliza, indeed, that is one potential explanation," continued Tom patiently. "Nevertheless, after investigating Ms. Verinder's background, the headquarters have discovered that she used to be a former researcher in Artificial Intelligence when she suddenly quitted her position last year and became a Secondary school teacher. Thus, we cannot possibly overlook the coincidence in this event. We suspect....."
"She's probably just sick of working with robots so want to try working with humans instead," contemplated Claire. "But if you ask me, humans are just as annoying as robots, if not even more so!"
"Yes, Claire, that is indeed a possibility, too," answered Tom, ignoring Claire's personal remark. "Nonetheless, we are tempted to suspect a hidden motive is behind such a dramatic move, which could well be to use these students as an experiment for an innovative development in the fields of artificial intelligence!"
"NO WAY! That's illegal and inhumane!" exclaimed Eliza in horror.
"Exactly," replied Tom. "That's why we need you to help us investigate on what she's really up to."
