Looking at the OP alone, I'd definitely side with Kalph, and I see no reason why not to. Unless Someone comes in and gives more of the chatlog that contradicts what Kalph said, which I doubt would happen, Ephi is completely in the wrong imo
Also why do so many people dislike Kalph? I mean I've had my arguments with him in the past, but in the last several months I haven't seen him do anything wrong
