In the commotion, someone had bumped into Lee from behind - it was Tina! The bump had caused Lee to drop one of the keys. "Here," she said, picking it up. He didn't seem to notice. Just as she was about to get his attention to hand it back to him, however, it caught the attention of one of the lizard creatures. Tina saw it coming after her and ran.
Jenny saw her take off and ran after her with the monster in hot pursuit, yelling louder as she noticed the creature now pursuing both of them, but the key primarily: "Tina, where are you... uh-oh! Tina!"
The creature seemed unrelenting in its pursuit. In their hurry, the girls scarcely even noticed where they were going - they were heading to the exit from the tunnels into the school library. Thinking quickly, Tina, who had just come up to the doorway, inserted the key she was carrying into the lock and opened it. "Come on," she yelled to Jenny. Jenny barely squeezed through as the door closed, cutting off the monster's access to the premises.
"So, what now?", Jenny asked.
"I don't know! Do you expect me to know everything?", Tina exclaimed.
"Whoa, calm down," Jenny said. "Am I not supposed to be the mean one here?", she continued, now grinning slightly.
Tina sighed. "Okay, let's figure out a plan of action. Lee probably needs this key downstairs, right? So I guess we should bring it back..."
"Always about Lee, eh?", Jenny asked with a smirk. Seeing Tina's hostile glare, however, she backed down: "Okay, okay... I guess you're right."
"We obviously can't go back that way," Tina continued. As if to reinforce her point, noises coming from behind the door they had just come through seemed to indicate the creature that had chased them was no longer the only one in the passageway they had used. "We're gonna have to risk going through the library. On three, okay?" Tina motioned towards the sliding door that was the exit from the small walled-off room that they were now in into the rest of the library. "One, two, three!" They opened the door together.
They almost immediately realized doing so was a mistake. Not one but two Cleaners came through the doorway, crystallizers pointed straight at them. They quickly realized they were caught; Tina was forced to surrender the key to one of them as both robots clearly prepared to fire at them.
Suddenly, a crystallizer beam from somewhere they couldn't quite see zapped both of the robots in question! They turned to see the librarian - that same librarian who they had been very certain was quite senile indeed - crystallizing both of the Cleaners with a single shot. "No way! We thought you were just..."
"What? A doddering old fool?", she said, eyeing them suspiciously.
"I was going to say, a nice little old lady, but..."
"Ha! How many clues do I have to give you girls? Really? I gave you info on Finnwich and the book. I directed you to the page on Coral Grove. For crying out loud, I even dropped that tidbit about having a date with Finnwich! Of course, that's nothing compared to... well... really, can you not see the family resemblance?"
The girls looked at each other, shocked. How blind they had been - how could they not have connected the distinctive chins before? Tina said, "Are you...", then trailed off and looked at Jenny; together, they exclaimed: "Are you Wurst's daughter!?"
"Finally you figured something out without me having to tell you!", the librarian said in an annoyed tone. Then her expression softened up ever so slightly, and she said, "Come on, girls! There's very little time left!"
"Time for what?"
"Why, to open the pyramid, of course! Let's go, before it's too late!" Before either of the girls could say anything, the librarian decrystallized the hand of the Cleaner holding the key and set it into the lock, opening the door to the tunnels.
