The Sand team manages to extricate from the Tower and back to their rooms without incident. The two of them that are not Elieyha are given strict instructions by their jounin to watch her carefully and not let her cause any trouble. Easier said than done. She really wants to kill someone, and he's only got so much chakra with which to run puppets to distract her. He and Tsubasa are not really at a level where they can be proper training partners long-term. He mentions as much to the jounin. A short time later, a collection of very interesting scrolls appears, some bearing the mark of the Leaf or clans belonging thereto. He leaves them where Elieyha can find them.
With the time this buys him, he can prepare for his match. Researching and preparing insecticides mostly, both gaseous and contact varieties. There's also the possibility that the bugs will latch onto his chakra strings, so he practices quickly breaking and reforming them.
