Christie's Gothita helped
Officer Jenny (Unova) try to figure out what was happening to the Tabunne.
Christie generally carries her Gothita around in her arms as she travels around.
Christie relies on her Gothita's
Telekinesis for attacking as well as for strategic movements. When they were tracking the Tabunne, she told her Gothita to use
Telekinesis to lift everyone over the gorge after the Tabunne wrecked the bridge so that they couldn't get across.
