Julian and OTA (Multiples Welcome)
It was completely true that Julian was a serious guy at times. But that didn't mean that he didn't know how to have fun. He totally did. It had just been a long time since he'd really had the chance, with the death of his father and the necessity of taking care of the children. Here, though, he didn't have those responsibilities, and while he was still trying to decide if that was good or bad, it did give him the chance to go to parties like this.
Even though he didn't really know any of the people celebrating, it was a good place to get to know them, and other Madison Valley people too. Networking was also important, although he certainly wouldn't admit that was one of the reasons that he was here. Or the fact that he was avoiding Emma.
