Seeing Sera shake her head at him then look back in his general direction, he had to hide his smile. She knew how competitive he is, so she shouldn't be that shocked he wanted to race, unless there was something more. It was going to be interesting having her on this trip, he wanted to be with her the whole trip, to tell her how even just her presents was enough to make him smile. She was one of the four people he thought about before going to sleep and when he wakes up. Her, his brother, sister and Ben, who he saw as a brother. But it was going to be hard, Zack was never the best at expressing himself expressly in front of others. On top of that even if he did tell her how he felt and she rejected it... how could they possible have fun the rest of the trip and how would it kill their current relationship. Could he risk everything to tell her or should he suffer quietly?
Thankfully before Zack's thoughts could go any deeper into how he felt about Sera, Ben broke his train of though by asking if anyone needed a rest. Which caught him off guard for a second but after Ben showed him were they were going and offer for people to keep going it clicked, it was for the girls not him. He turned to Tessa would had agreed to the race which made him smile, though Ben wasn't racing, to bad could have used the win after the surfing contest, this was going to be fun. She was cute but she was no Sera and she is Jaspers girl, but that didn't mean he couldn't have some fun. He glanced back to see who was coming and who was stay but turned back to Tessa as she asked, “So am I competing against a pro here?” which made him laugh a little. "I don't know if I would call myself a pro but... look at these calves." he said in the friendlies and proudest voice he could. As they walked he motioned to his calves which he was proud of, they were very well defined, when he wasn't surfing he was hiking or running. Should he let her win or should he go all out or some were in between? All well, guess what happens, happens.
