Justin

Justin is a rather protective older brother to his younger sister, Kara Silver. He may come off as a poser or someone who's trying to act cool, he's actually rather nerdy. He loves science and helps his father with his duties. He hates splicing others but takes it as a learning experience when he is ordered to do so. 

Justin is very low-key and you'd never guess he'd be into other men, however he is very open about it, if you question him on the topic. 

He tends to be a bit overprotective of Kara at times, causing him to be annoying to her. However, he only means well. He wishes the best for anyone he cares about deeply.
