Awh...he'll always have a voice in his head to keep him company. Best Friends Forever I'd say!...unless the voice starts telling him to burn things...theeeeeen we might have a problem
I think the voice in his head is an enabler.
I have, in a veeeery tiny way, hinted at the voice in his head's identity in one of the strips. I will never say what or where that hint is, however. (Lesse if anyone postulates correctly.)
OH SNAP!, I think I know now. I believe I saw a hint in this strip, or at least a vague idea of the identity of the Voice.
