First off, you gave eepos a chatbot to teach him something?
Eepos has plenty of knowledge of TorqueScript, a chatbot is one of literally the easiest things to create, if you didn't know eepos knew TS, then you guys weren't "friends" in the first place.
Second, releasing add-ons isn't some sort of offense, if you make something, and give it to someone you barely know, it's not longer private. He didn't steal it from you using an RAT or some stuff like that.
Finally, he didn't "betray" you, because for all you know he's just trolling you, and doesn't even plan on actually releasing stuff, he even said he only wanted the reaction which you already gave him
