Party Brother, PB, Laruto. Lars took a few days off from getting drunk to hang out with TV (and by extension Mitch) when he first joined Chronos' gang to get to know him... Though at the time, TV was still struggling with his troubles that he had accumulated from the start of the toxin spill. So he wasn't the best conversationalist even with Mitch near by, but TV did warm up to the guy after a few months! And Lars quickly became one of his other favorite people, because he was fun and he made the world a lot less scary... Much like Mitch did, but with more parties- and drinking. At least a little drinking for TV.
BB, TV's big brother; not by blood but at this point that doesn't even matter. He's the closest thing TV has to family, at least until they joined Psyke. But for three years they survived together. They had their ups and downs, their attempts at finding normality in their new environment. Like playing games, or Mitch trying to help TV keep up his ability to read and at least do basic math. Overcoming struggles together against the world.
Big Bro. Ruska loves to pester and tease him but won't admit to just how much he admires him. Remembering how Isao had protected both him and his sister during their time alone in the Aftermath is what inspires Ruska's desire to be Better, Faster, Stronger in order to protect what's left of the things he cares about.
The love of his life. Chronos thought that after losing his wife Farrah that he'd never love again, but he was wrong. Artemis is a caring, strong, and beautiful woman, and he loves every moment he spends with her. Meeting her is one of the best things that came out of the fallout.
