1: Josh didn't clench his fist to "shrink" the energy, he clenched it to try and hide it, (As he once did in a previous post when the energy formed while he was sitting in a compartment), hehad no idea he could disperse the energy at this time, thereby the energy dispersing as he un-clenched his hands was "teaching" Josh that he can disperse the energy by clenching it. I understand I probably should have explained this better so I apologise.
2: If it seemed that my character attacked with his powers than I assure you this was completely unintentional. Joshs powers are directly linked to his hatred, meaning that they are very uncontrollable. Hatred is an emotion that can stem from anything and can be caused by anyone, anger can stem to hatred, sadness can stem to hatred, jealousy, pit, malice, almost all negative emotions if left to fester turn to hatred. Making it very very easy for Josh to lose control, as seen by Josh barely able to stop balls of energy forming when he is a state of extreme hatred. You said Josh has an extent of control over his powers. When in truth he has less control than every one else, I wasn't going to reveal this until later (even though it was quite obvious anyway) but Josh has no control as to when his powers activate and most likely never will. Another thing I wasn't going to reveal until later, was that Josh is absolutely terrified of his powers and himself, he won't show it in front of others but when Josh is alone he is a very fragile and insecure person, he can barely remember what he has done or control his actions when his powers are fully active, which so far they have not and even now he can barely think straight when accidentally using them. So in retrospect Josh has and always will have a lesser extent of control over his powers than anyone else has and always will.
3: Joshs behavior is erratic for two reasons. one, he hasn't had any contact with others in his age group in quite some time, most likely due to his time in a firggin mental asylum, I mean come on can you not put two and two together. Two, he is slowly encasing himself in a hateful emotionless shell. His words and thoughts are bordering between hateful and kind because he is fighting an ongoing battle with himself. In all honesty my second choice for Joshs inner demon was confliction but that can only go so far so I chose hatred instead. His father has inspired a burning hatred for people, but prior to that he was a completely different person, he was kind and considerate (shown by his helping of the freshman, his hatred towards Edward inspired by his leaving Cody out to dry and him stealing his mothers life savings, and his NOT attacking Kieran when Kieran had grabbed him earlier) Speaking of which I don't mean to be rude but I don't believe you have any right to question me of all people on bunnying, I simply changed the events so that Josh wasn't bunnied and Kieran was bunnied as little as possible, whereas you threw two characters to the ground after beating them AND you had Josh Thrown Off The Back Of The Train, I mean seriously Ichiro come on, you didn't have my approval for any of that and it greatly offended me. If my bunnying offended you then I'm sorry but I was just undoing the damage done against Josh.
4: I understand my RPing may have been slightly extreme lately and I apologise, but I am going through a very emotionally unstable time right now IRL due to a death in my family and if any of you insist on prying further into the matter then I suggest you personally bring it up in a VM.
I hope this explanation into my characters psyche was enough to explain it to you. If you still have further questions then by all means ask them, I will answer them.
