I was under the impression that the show was entertaining writing him out, and switched things at the 11th hour. The fact that Ross hasn't really had anything to do until Debbie returned somewhat raised my suspicions too. The issue with Ross is that they only give him story when Debbie is on the canvas. He's only relevant to the writers when he's in Debbie's orbit, and I hate that. I feel that Ross could be so much more out of Debbie's orbit.
