[X] No! You're going to keep pushing this matter. You have to have him open up to you or he will keep getting into scuffles with Tycho. You need to show him that you're a reliable teacher that is always available to help.
[X] Maybe you should back off. As a fellow solitary creature, you can tell that he wanted to be left alone. Maybe he would be insulted if you don't trust him to handle his own problem. He was a delinquent after all.
[x] If he refused to open up, fine. Send him to the guidance counselor, Mr. Eagle. If he refused your help, then maybe Mr. Eagle will have a better chance than you do. He was the go-to person for help after all.
