The inn was a trap designed to keep Trevor and the others locked inside while the Team Flare scientists Aliana and Mable attempted to take X's baby Kangaskhan, Li'l Kanga, while he wasn't looking. Trevor, Y, Tierno, and Shauna stayed at an inn for the night while X slept in the tent on Y's Rhyhorn's back. In Inn-teresting Developments, the group arrived in Aquacorde Town.
Trevor and his friends then set off on a journey, together for the first time in years. Once X was retrieved, Y decided that with their home destroyed, the best option was to leave town. Using her Rhyhorn racing skills, Y managed to get Trevor, Tierno, and Shauna to safety, but an explosion sent the case containing Fennekin's Poké Ball and Pokédex flying.
The Legendary Pokémon Xerneas and Yveltal then appeared in Vaniville Town and began fighting, causing mass panic and destruction. He hoped that by presenting one of the starters to X, he would give up his shut-in ways and go on a journey with one of them. Later, Trevor went home to pick up a package containing three starter Pokémon and three Pokédexes from Professor Sycamore. He was first seen watching one of Y's failed attempts to get X to leave his house and come outside. Trevor debuted in An X-cuse to Come Out and Play. Pokémon Brilliant Diamond and Shining Pearl.
