A New friend

On the way to Riko Island, Danny and Dave barely spoke to one another. They kept giving each other this weird look which will make the other person look away. After sometime, Dave felt uncomfortable and broke the silence;

Dave: Why do you keep staring at me like that?

Danny: I was about asking you the same thing

Dave: If you have got something on your mind, then spit it out

Danny: Well the only thing I have got in my mind is why you have changed so much and especially towards me? You and I were not like this before. We were not just brothers, but best friends. And now, you are so serious with training you rarely have anytime for fun
