Estranging himself for years after that event, much changed when a new neighbor moved into town. Explained by his mother, renowned Rhyhorn racer Grace and her daughter Serena were moving into Vaniville Town - though to Calem, he didn't care as it didn't involve him. Having received a letter from Professor Sycamore regarding Calem, Calem's mother urged that Calem show Serena around Vaniville Town before taking her off too Lumiose, as the Lumiosien professor was waiting upon them both. Annoyed and reluctant, the once shut-in Calem did as he asked - and just like that, Serena had thrown Calem into an adventure he didn't ask for.
Just after the day Calem toured Serena around Vaniville, he was forced to meet his old friends - Trevor, Shauna, and Tierno. Although it's been years since the KJT incident, Calem long stopped talking to his friends, and after a while, they stopped visiting. Meeting them again was tense, though Calem refused to speak with them as much as he had to. He hated being reminded of the last and the awful vulnerability he felt from it. It was awfully difficult want Tierno presented him with some Pokeballs filled with some Pokemon. Tierno's mother was a dancer in Lumiose and had met with Professor Sycamore, who bestowed her with a handful of starter Pokemon for Tierno and his friends. In the end, Calem had picked out a blue-eyed Fennekin - a curious deviation that stuck out to Calem as odd.
Still, if that wasn't enough to stir up Calem's usual routine, he blamed Serena as the turning point of when his life was thrown into chaos. Just a few days after picking out Fennekin, Kalos' lengendaries Xerneas and Yveltal were mysteriously reawakened and engaged each other into a massive fight across Kalos. In the aftermath of their fighting, Vaniville Town was torn to ruins and Calemn found himself leaving to Lumoise earlier than planned - with Serena, Trevor, Shauna, and Tierno just behind him.
Upon arriving to Lumiose City, Calem felt overwhelmed by the large city and it's endless sea of lights. It was nothing like Vaniville Town were everyone knew everyone and everything that was going on in the small town. Lumiose was engulfing, enchanting, and Calem felt so small and insignificant to such a grand city. Even though he was accompanied by Serena, Shauna, Trevor, and Tierno, Calem felt absolutely alone.
When the group met Professor Sycamore down at the Lumiose Pokemon Lab, a strange feeling awoke inside Calem. From all that he knew about the Professor, the Professor was odd as the rumors said, but also just as kind and warm. But that still felt strange, and as he saw Sycamore being cheery with everyone else, a lump would grow in Calem throat and he found himself hating the Professor. Just like Serena, it was Sycamore that forced Calem to leave the safety of his home and be thrown out to the world... Though deep down, Calem was afraid to entertain another idea, one that he didn't understand himself just yet as he felt a pool of jealousy seep into his gut as he saw Serena hug Sycamore gleefully.
Enter Calem, a lone, washed-out Pokemon trainer. With absolutely no social skills and unsure goals for the future, Calem is lost about where to go in his life. Having no true desire to become the Kalos champion and facing the world of popularity as a social outcast, Calem is lost. Years ago, life used to be so simple when there was a strong light in his life, but where did it go? His parents were so hopeful that he'd find himself again in the world, and now he's a afraid he's learned too much about himself in the dark.
