Might sound corny but.. do you have a favourite character that didnt play that large of a role but you would like to see more of him/her?? for me i love Kuriarare Kushimaru!! i wish i could have seen more about him ahahah 
no... she got a lot of that in the pein arc... but she has been forgotten nw.... but not as much as neji has though..... and he's supposeed to be the strongest of the hyuuga clan....more hinata would be nice
