Mauvaises graines

White Chapel's oldest tree has been cut down, and the tree takes its revenge by growing weeds into the school's computer system.

Rory becomes possessed by the tree, and Ethan, Benny, and Sarah must stop it without hurting Rory. Ethan has an idea: to hack all the computers in the lab with a virus. He acts upon his idea and all the computers shut down. The tree is destroyed and Rory is saved.
