My aggressive overanalyzing has led to a conclusion: the knight (or at least the shadow of the knight) is FRIEND, and my reasoning isn't easy to refute: "that chair is going to kick your ass"
ALL of the ball fortunes pertain to chapter 3, even the one about mizzles, so necessarily the chair-based ass-kicking happened in chapter 3. But where? Where did the chair kick our ass? The only ambiguous and difficult fights in the entire chapter were the knight and ERAM, and even then ERAM's dialogue ("enough of that, we both have work to do") heavily implies that they're the knight anyway.
There really aren't any alternatives.
FRIEND is the knight.
