We are the best.
Three predators looked at a 3D hologram of their destination. They had arrived. They activated escape pods which took them to earth. The pods landed, and everyone took a look at their surroundings. One of them noticed a sign, which read "welcome to St Trinian's school for young ladies." St Trinian's he thought. I hope there is a lot of worthy prey around. He ordered the other two to scout around the building, before tripping over something. The yautja scanned the area, but saw nothing on any of the spectrums. He magnified his view and tried again. This time the hunter saw a very small wire. He told the other predators to be wary of any other traps. They entered the building.
Inside: The geeks were woken up by their computer, which was telling them that one of the traps had been activated. They woke up the other girls, who prepared to fight off the intruders. They were surprised at the fact that seven foot tall "people" would be wearing armour. And the fact that they closely resembled humanoid reptiles. With very deadly looking weapons. The girls set up a trap, the same one that they had used on AD1 a few years earlier.
The Yautja heard soft singing; "We are the best, so screw the rest. We do as we damn well please. Until the end, St Trinian's. Defenders of anarchy." This confused the hunters as: one they had no idea what most of the words meant, even with their translators, and two the soft meat seemed to be deliberately trying to attract their attention. As if they knew they were there. The predators re-activated their cloaking shields.
"Wait. Wait." murmured Annabelle Fritton, head girl of St Trinians. Most of the students were lined up in ranks with various throwing weapons, ranging from eggs to knives. Everyone else was busy setting traps, including Camilla Fritton, Annabelle's aunt and head mistress.
