Hey I'm doing two characters as well. I know you asked how to go about it, here's my advice,

They at tools for your story. If one says something and the other doesn't need to, don't force the other to say anything.

They are paints to your canvas. You have red and blue. Don't use red just because its there. Paint your own picture!!! 

Hope that made sense and/or helped.

Also, mixing red and blue too close together far too often usually ends in an ugly shade of gray all over the canvas.
