Caleb produced some of the weirdest drama. Like the part of the show when they initially introduced the possibility of Dylan being a incest rape-baby and Dylan getting mad at Norma over it...? That stuff was real questionable. But still, Dylan has had some of the best parts, too, usually when it came to Norman more than Norma.
The whole never knowing when Caleb wants something or if he's trying to help makes it hard for me to decide how to interpret him, and I guess that might be intentional but the cast seem to all have well-determined opinions of him that can be a tad ill-defined.
Other than some of the questionable choice of Dylemma abandoning Norma(n) and being iffy on Caleb, Norman's stuff was generally enjoyable in the expected awkward Norman way.
